analytic_rank crashes #1234

zimmermann6 · 2007-11-21T14:04:25Z

Maybe the following is not feasible, but analytic_rank could crash smoothly.

sage: d=100032426715415089/251987961355200625
sage: E = EllipticCurve([0, -d^3+5*d^2, 0, -8*d^5+8*d^4, 4*d^8-8*d^7+4*d^6])
sage: F = E.minimal_model()
sage: F.analytic_rank(algorithm='cremona')
<type 'exceptions.RuntimeError'>: Error: '  *** elltors: precision too low in torsell.

sage: F.analytic_rank(algorithm='rubinstein')
<type 'exceptions.TypeError'>: unable to convert x (= 6.90579e+20 and is too large) to an integer

sage: F.analytic_rank(algorithm='sympow')
sympow 1.018 RELEASE  (c) Mark Watkins --- see README and COPYING for details
**ERROR** c4 invariant is too large

From John Cremona: the "cremona" version just wraps a gp script, which
needs to have sufficient precision even for ellinit() to work ok here.
Unfortunately this call will run in its own gp session, and it is not
possible for the user to set the precision. (I found the same while
running a lot of examples through Denis Simon's gp scripts). The
solution is to change the wrapper to have a precision parameter, with
some reasonable default for backwards compatibility, which gets passes
through to gp.

NB I think that all functions which wrap gp scripts should have the ability to set various gp defaults before the scripts are run. Notably the real precision (which is the culprit above), but also in other cases.

This should be easy but tedious -- is there anywhere a list of which functions operate by running a gp script?

Still an issue with Sage 2.10.2.alpha0.

I can only speak for the first of these, begin responsible for the gp script which computes analytic rank.

This curve has conductor N=690579402364042119390 which is vastly too big for the analytic rank algorithm anyway (it requires the computation of O(sqrt(N)) terms of the L-series).

Also relevant here is that my analytic rank gp code is old. When Magma adopted it, it was vastly improved (by Mark Watkins), which means that for several years I have not used my own gp program at all, let alone developed it. For this curve, I don't think even Magma would succeed in computing its analytic rank.

Given the fundamental problem that computing the analytic rank increases rapidly with the conductor N (I think it is sqrt(N)), one solution would be to impose a (carefully-chosen but necessarily somewhat arbitrary) cutoff N_max, so that asking for the analytic rank of a curve of conductor>N_max would result in an error.

One way to implement this would be to have N_max a parameter to the analytic rank function, with a default value of (say) 10^6 or 10^7. (I would have to do some experiments to decide on a sensible value). The docstring could explain that the user is allowed to increase this but warn that it may take (effectively) for ever.

JohnCremona · 2008-06-26T08:23:04Z

comment:7

PS The vale of N_max would presumably be different for the different algorithms supported (sympow, lcalc, etc). I was only thing of the "cremona" algorithm. I also note that the docstring claims that lcalc is the most efficient, but cremona is the default -- that was not my decision!

The attached patch cleans up the exceptions raised, as requested. Also, in the (default) case where Cremona's gp script is used, the precision is automatically doubled until it doesn't fail. I also start the precision at 16 rather than the default, since it will get automatically double if necessary, and it's about 3 times faster usually by using this smaller precision to start:

Review: excellent and well done. Applies cleanly to 3.3.alpha0 and all tests in elliptic_curves pass.

Suggestion: I see that for EllipticCurve([1234567,89101112]) which has conductor 61928339435779485920, sympow and rubinstein know they are beaten and quit, while cremona just takes a long time (I did not wait). It might be a good idea to work out a sensible conductor limit for my gp script and have sage only call the script if under that (perhaps with a parameter to allow users to override it). But that would depend on many factors (speed of machine etc), and this patch should not be delayed because of that.

Pass!

I also was testing the patch, but John was faster than me. Just a comment: it would be better to capitalize
people names (rubinstein -> Rubinstein, weierstrass -> Weierstrass), at least in the documentation
(for the options, it might involve too much work).

I agree with capitalization in documentation; for parameters it would probably be best to allow either.

This PR aims to implement Drinfeld modular forms into SageMath. These special types of modular forms live in the function field theory and are linked with Drinfeld modules. #### Definitions Without going too much into the details, we give some definitions and insight of what is going on here. Let $K = \mathbb{F}_q(T)$ together with the $1/T$-adic norm and $A = \mathbb{F}_q[T]$. We define $K\_{\infty} = \mathbb{F}_q((1/T))$ be the completion of $K$ and let $\mathbb{C}\_{\infty}$ be the completion of an algebraic closure of $K\_{\infty}$. In this specific setting, the *Drinfeld period domain* of rank $r$ is $$ \Omega^r(\mathbb{C}\_{\infty}) := \lbrace (w_1, \ldots, w_{r-1}, 1)\in \mathbb{C}\_{\infty}^r : \text{the }w_i \text{'s are }K\_{\infty}\text{-linearly independant} \rbrace. $$ (this period domain is to be seen as the analogue of the complex upper half plane) So, for each $w = (w_1, \ldots, w_{r-1}, 1)\in \Omega^r(\mathbb{C}\_{\infty})$, we have an associated $A$-lattice (i.e. a discrete projective $A$-module of rank r): $\Lambda_w = A w_1 + \ldots A w_{r-1} + A$. The analytic theory of Drinfeld modules tells us that, for each such $w$, there exist a Drinfeld module $$ \phi^w_T : T \mapsto T + g\_1(w) \tau + \ldots + g\_{r-1}(w) \tau^{r-1} + g\_r(w) \tau^r $$ associated with this lattice. This association is what we call the universal Drinfeld module over $\Omega^r(\mathbb{C}\_{\infty})$. We see the coefficients as functions $g_i : \Omega^r(\mathbb{C}\_{\infty}) \rightarrow \mathbb{C}\_{\infty}$. These functions satisfy modular transformation property under the action of the group $\mathrm{GL}_r(A)$: $$ g_i(\gamma(w)) = j(\gamma, w)^i g_i(w) $$ where $j$ is some automorphic factor. The ring of Drinfeld modular forms for $\mathrm{GL}_r(A)$ is $$ \mathcal{M}\_{\bullet} = \mathbb{C}\_{\infty}[g_1, \ldots g_{r-1}, g_r]. $$ #### Implementations details In this implementation, we create a new parent `DrinfeldModularForms` which represents the polynomial ring $K[g_1,\ldots, g_{r-1}, g_r]$ and a new element class `DrinfeldModularFormsElement`. Then, for arbitrary rank, we only see a Drinfeld modular form symbolically as a multivariate polynomial in $g_1, \ldots, g_r$, the coefficients forms. In the special case when the rank is two, we aim to implement algorithms for computing the expansion at infinity of any Drinfeld modular forms. These expansions are analogues of the usual $q$-expansion of classcial modular forms. This will be achieved via the Lopez-Petrov nonstandard expansion theory. We note that this implementation was initially done as a pip-installable package: https://davidayotte.github.io/drinfeld_modular_forms This work has been an ongoing project for almost two years now and since the addition of Drinfeld modules in SageMath, the author has seen an interest in the implementation of Drinfeld modular forms to SageMath. In the rank two case, the ability to compute their expansion at infinity shows some interesting computational properties of these objects. We are aware that this is a quite specialized topic, so we aim to make this implementation as convivial as possible for the user and well documented. Any comments and suggestions are welcome!

…ensional Lie algebra representation   The goal of this PR is to implement the BGG resolution of a finite dimensional simple Lie algebra representation $L_{\lambda}$. In order to implement this, we need to implement a number of features: - Simple modules (this does not assume finite dimensional). - Dual modules in BGG category $\mathcal{O}$. - Fix embeddings of Verma modules sagemath#36793. - Improve construction of elements of free abelian monoids when strings are indices. - Move `to_root_vector()` to a method of fundamental weights and cache the inverse Cartan matrix. - Add `is_dominant_weight()` method to weight lattice realization elements. - Add `is_verma_dominant()` to define a dominant weight in the sense of the Humphreys 2008 reference, which means the Verma module is projective (that is, maximal in its dot action orbit). - Add the category of `FiniteDimensionalKacMoodyAlgebras`. - `@cache_in_parent_method` marked `weak_le` for Coxeter groups. - Subclass of PBW bases for semisimple Lie algebras. We also add methods to compute the contravariant form of a Verma module and add tester methods for them being simple or projective. It is possible to split this up into smaller parts, but it is natural for them to go together given the final goal. One major TODO is to speed up the computation of the bases of the simple modules. The main place to optimize this would be to improve the multiplication of the PBW basis code, which for finite dimensional Lie algebras (not necessarily semisimple), this could be improved by using the fixed basis order and using the monomials as vectors to avoid lots of calls for getting the sort order and comparing. In particular, the triangular sorting order for the Chevalley basis implementation has error messages being raised (and caught) for comparing the roots and coroots. This will be done at some point on a separate PR.    ### 📝 Checklist     - [x] The title is concise, informative, and self-explanatory. - [x] The description explains in detail what this PR is about. - [x] I have linked a relevant issue or discussion. - [x] I have created tests covering the changes. - [x] I have updated the documentation accordingly. ### ⌛ Dependencies   URL: sagemath#37297 Reported by: Travis Scrimshaw Reviewer(s): Matthias Köppe, Travis Scrimshaw

…TRAINT=$SAGE_ROOT/constraints_pkgs.txt`   This is aimed at the intermediate level, for users who wish to build a set of distribution packages as supplied in `pkgs/` but without using the wheelhouse infrastructure of Sage-the-distribution. Documentation included in the files. It can also be tested using new tox environments defined in `pkgs/sagemath-standard/tox.ini`, and is tested on GH Actions: https://github.com/mkoeppe/sage/actions/workflows/ci-linux- incremental.yml?query=branch%3Aconstraints_pkgs - this also provides the missing automatic test for the **sagemath- standard** distribution built out of `pkgs/sagemath-standard/` Marked as critical because it is hoped to ease the adoption of modularized distribution packages by downstream packagers.    ### 📝 Checklist     - [x] The title is concise, informative, and self-explanatory. - [x] The description explains in detail what this PR is about. - [ ] I have linked a relevant issue or discussion. - [ ] I have created tests covering the changes. - [ ] I have updated the documentation accordingly. ### ⌛ Dependencies   - Depends on sagemath#38515 (merged here) - Depends on sagemath#38500 (merged here) URL: sagemath#37434 Reported by: Matthias Köppe Reviewer(s): François Bissey, Kwankyu Lee, Matthias Köppe
