2020-04-23 09:07:44 +0100 | commented answer | lifting modular symbols for newform of level 35 at p = 5, 7 One solution would be to express the K-valued modular symbol (K = NumberField(x²+x-4)) as a K-linear combination of QQ-valued modular symbols and do the procedure for the latter ones. I'm working on this. |

2019-09-23 15:58:16 +0100 | asked a question | lifting modular symbols for newform of level 35 at p = 5, 7 Let $f$ be the unique normalised eigenform in $S_2(\Gamma_0(35))$ of dimension $2$. It has split multiplicative reduction at $p = 5$ ($a_p = +1$) [and non-split multiplicative reduction at $p = 7$ ($a_p = -1$)]. The $p$-adic $L$-function should vanish to the order $1$ at $1$ (because the associated abelian variety has rank $0$). I want to compute the valuation of its leading coefficient using Pollack-Stevens. To do so, I use the following code: Unfortunately, the last command fails after a few seconds (also for $p = 7$) with a
Is there a theoretical problem with computing the $L$-value or is there a problem with the implementation? |
