Jennifer S. Balakrishnan, William Craig, Ken Ono

We consider natural variants of Lehmer's unresolved conjecture that Ramanujan's tau-function never vanishes. Namely, for we prove that $$τ(n)\not \in \{\pm 1, \pm 3, \pm 5, \…

William Craig, Peter A. Linnell

We prove that a uniform pro-p group with no nonabelian free subgroups has a normal series with torsion-free abelian factors. We discuss this in relation to unique product groups. W…
