I encountered the following problem: s is the trivial submodule of quo, where quo is a quotient module of modular symbol space. The zero element b of quo should be an element of s, but sage says no when I do the following process:
S = ModularSymbols(Gamma1(13),2).cuspidal_subspace() ker = S.module().subspace([0]) quo=S.module()/ker s = quo.submodule([]) a = (0,0,0,0,0,0,0,0,0,0,0,0,0,0,0) aa=S.module()(a) b=quo(aa) b in submodule it gives FALSE Anybody has any idea where I am wrong?
