LMFDB Work

Revision as of 19:40, 9 October 2015

List of some places that need work with examples. Please email Holly when you inevitably find more!

• Math mode in Gaga boxes

• List of LMFDB conferences/workshops and make webpages for them

• Maass Forms- (assigned to Stefan)

Clicking on browse produces a server error

http://beta.lmfdb.org/ModularForm/GL2/Q/Maass/BrowseGraph/1/10/0/10/

• Maass Forms- (assigned to Stefan)

Under displaying coefficients for a form, there is a search box without any explanation of what an acceptable entry is or submit button

http://beta.lmfdb.org/ModularForm/GL2/Q/Maass/4f5558cb88aece2646000014

• Siegel Modular Forms-

In browsing by weights, 1-100 doesn't work, but the subset 20-30 works fine.

http://beta.lmfdb.org/ModularForm/GSp/Q?page=dimensions&level=17&group=Sp4Z&weight_range=1-100

• L-functions- (assigned to Sally or David)

Problem with some Z-functions graphs, for example RH is false? If you go through the modular form it's bad, but through the elliptic curve it's ok.

problem: http://beta.lmfdb.org/L/ModularForm/GL2/Q/holomorphic/14/2/0/a/0/

fine: http://beta.lmfdb.org/L/EllipticCurve/Q/14.a/

• L-functions- (assigned to Sally)

L-function display alignment issue at least on some browsers

http://beta.lmfdb.org/L/Character/Dirichlet/3/2/

• L-functions- (?)

If you choose to tensor product two elliptic curves, then select a random elliptic curve in each box and click on “tensor these”, you get a server error

http://beta.lmfdb.org/TensorProducts/show/?obj1=EllipticCurve%2FQ%2F272080%2Fl%2F2&obj2=EllipticCurve%2FQ%2F132800%2Fc%2F1

• Elliptic Curves- (assigned to John Cremona)

Picture looks weird; smaller; numbers just off the edge http://beta.lmfdb.org/EllipticCurve/Q/102/b/

I (JEC) do not understand the problem. Which numbers are off which edge? If you want to the isogeny class to be smaller I have been working on that.

• Elliptic Curves- (assigned to John Cremona)

If I want to look for a curve whose Jacobian has torsion Z/29Z, I'm supposed to write [29] in the "torsion" field, and this works; however, if I forget teh brackets and just write "29", it produces a server error. I think this should be changed either into an explicit "syntax error" message, or (better) make the search more clever so that it understands 29 as well as [29]. http://beta.lmfdb.org/Genus2Curve/Q/

The same issue for elliptic curves has been fixed (for curves over Q): check it out at beta. It would be easy to adapt that here. More seriously: the search page seems to suggest that the torsion can have at most 2 cyclic factors, but it it should be at most 4! Pull request #383 deals with this -- but error handling of the input on this page is almost nonexistant still.

• David will email Pascal about issue with Hecke characters

• Classical Modular Forms:

When you put something inappropriate into a search box, instead of letting you know as in the elliptic curves page, it gives a server error. http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/ranges?level=r&weight=&character=0&Submit=Search gives a TypeError: coercing to Unicode: need string or buffer, int found

General: wrong fields of coefficients, and too large display. Choose better generator for field of coefficients.

On http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/9/12/1/ , the coefficents of form c are defined in terms of a2, which is not defines clearly - all that is clear is that it lies in Qsqrt70. Besdies, clicking on form c reveals that a2 is actually 6sqrt70, and not sqrt70 as one might think. This is extremely confusing. Maybe it would be good to have a script looking at the modular forms in the database, searching for the field of coefficients in the database of number fields and replacing the coefficients with a new expression in terms of the generator that is in the database?

http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/23/12/1/

Page does not load (it only does once in a while): http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/23/10/1/

Crash trying to use truncate_powerseries: http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/24/8/1/ http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/24/10/1/

Error message: "Problem with Hecke orbits in the datbase!": http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/24/12/1/ http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/18/6/1/

General (wishlist): Need more that 100 coefficients for the data to be useful

Search for a weight >=26 crashes: http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/ranges?level=&weight=26&character=0&Submit=Search produces AttributeError: 'str' object has no attribute 'get'

Range searches don't work (not implemented?): neither level nor weight

Search for Gamma_0 redirect to search for Gamma_1

dimension not clickable: http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/9/10/

This incorrect url should give an error instead of redirecting (confusing): http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/11/2/0/a/

Wrong root of unity is defined: http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/13/4/4/

Also, a wish list! Please also email Holly with things you would like to see here.

• In general, the database/website should be explicit about what it knows and doesn't know, for example, the ranges that are available for downloading coefficients of modular forms. It shouldn't give you a server error every time a page doesn't exist or information is not in the database.

http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/51/2/0/

• Classical Modular Forms-

Add Eisenstein forms, with toggle for viewing all forms, only cuspforms, or only newforms.

• Elliptic Curves-

Add higher rank elliptic curves

• Galois Groups-

A knowl or would be nice to explain the notation or origin of name for the uglier groups.
