Thank you anyway! 2020-04-23 09:11:02 +0100 commented answer PyCharm for SageMath on Linux Only one problem left: How can I use Sage specific syntax (^ instead of **, for example) in PyCharm when not using sage -sh? 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. 2020-04-19 15:16:33 +0100 received badge ● Scholar (source) 2020-04-19 15:16:29 +0100 commented answer PyCharm for SageMath on Linux The problem was that PyCharm used its own python interpreter, not the /usr/bin/python one. I changed it and now it works. 2020-04-19 12:55:46 +0100 commented answer lifting modular symbols for newform of level 35 at p = 5, 7 I think one does not need to $p$-stabilize when p | N: http://math.bu.edu/people/rpollack/Pa... However, only calling phi1.lift instead of phi1.p_stabilize_and_lift also fails.

The two most obvious choices seem to be PyCharm and Eclipse, but PyCharm is not able to do from sage.all import * even though my SAGE_ROOT="/usr" and I am running pycharm from a sage -shas described in https://ask.sagemath.org/question/397... or https://ask.sagemath.org/question/387.... 2020-04-19 11:49:01 +0100 received badge ● Supporter (source) 2019-09-25 04:00:26 +0100 received badge ● Good Question (source) 2019-09-25 03:02:28 +0100 received badge ● Nice Question (source) 2019-09-24 09:51:45 +0100 received badge ● Student (source) 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: from sage.modular.pollack_stevens.space import ps_modsym_from_simple_modsym_space A = ModularSymbols(35,2,1).cuspidal_submodule().new_subspace().decomposition() p = 5 prec = 2 phi = ps_modsym_from_simple_modsym_space(A) ap = phi.Tq_eigenvalue(p,prec) phi1,psi1 = phi.completions(p,prec) phi1p = phi1.p_stabilize_and_lift(p,ap = psi1(ap), M = prec)  Unfortunately, the last command fails after a few seconds (also for $p = 7$) with a RuntimeError: maximum recursion depth exceeded while calling a Python object Is there a theoretical problem with computing the $L$-value or is there a problem with the implementation?
