Factoring Hecke polynomials modulo a prime
J. Brian Conrey, David W. Farmer, Peter Jake Wallace
Let T^{N,chi}_{p,k}(x) be the characteristic polynomial of the Hecke operator T_p acting on the space of cusp forms S_k(N,chi). We describe the factorization of T^{N,chi}_{p,k}(x)…

Counterexamples to a conjecture of Lemmermeyer
Nigel Boston, Charles Leedham-Green
We produce infinitely many finite 2-groups that do not embed with index 2 in any group generated by involutions. This disproves a conjecture of Lemmermeyer and restricts the possib…
