Let Fn be the set of cuspidal automorphic representations π GLn over a number field with unitary central character. We prove two unconditional large sieve inequalities for Hecke eigenvalues π∈Fn, one on integers and primes. The second leads to first zero density estimate family L-functions L(s,π) associated which we make log-free. As an application estimate, hybrid subconvexity bound L(12,π) su...
