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:
 
Documenting the structure of the code: http://scripts.mit.edu/~kedlaya/wiki/index.php?title=Classical-mf-structure
 
 
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/
 
 
"Show more coefficients" is maxed at 87 even though 100 coefficients are stored. Crash when trying to download more than 100 coefficients.
 
http://beta.lmfdb.org/ModularForm/GL2/Q/holomorphic/1/12/1/a/
 
 
======
 
 
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.
