Hecke polynomials for small primes on newform and newspace pages #2759

Open roed314 opened 5 years ago

roed314 commented 5 years ago

It would be nice to see the characteristic polynomial of Hecke operators for several small primes (e.g. 2, 3, 5 and 7). This could be done both for spaces and forms, for dimension up to some bound (e.g. 100). For forms of dimension up to 20, this information is present in the algebraic q-expansion, but not easily extracted.

Agree with this! Especially for spaces, this was one of the first things that people tabulated, and it is a nice snapshot of all the forms in a space.

FYI, the data is available in the table mf_hecke_lpolys, see http://www.lmfdb.org/api/mf_hecke_lpolys/

@edgarcosta, does that make this a good first issue for tomorrow or another LMFDB Friday?

edgarcosta commented 4 years ago

I think so. Do we agree that we would like the display to look like HGM families at the end of the page? eg: https://beta.lmfdb.org/Motive/Hypergeometric/Q/A14.2_B8.3.1
