A Note on the Dimension of the Largest Simple Hecke Submodule
Abstract
For k ≥ 2 even, let d_(k,N) denote the dimension of the largest simple Hecke submodule of S_k(Γ₀ (N);Q)^(new). We show, using a simple analytic method, that d_(k,N) ≫ k log log N/log(2p) with p, the smallest prime co-prime to N. Previously, bounds of this quality were only known for N in certain subsets of the primes. We also establish similar (and sometimes stronger) results concerning S_k(Γ₀ (N),χ), with k ≥ 2 an integer and χ an arbitrary nebentypus.
