Title: Reducibility of polynomials under specializations
Abstract: Given an algebraic family of irreducible polynomialsf(t,x) ∈ ℚ(t)[x]that depends on a parametert, how large is the set of rational values t=t0for which f(t0,x) ∈ ℚ[x] is reducible? When is it infinite?
We shall discuss this problem, its role in arithmetic geometry, applications to arithmetic dynamics, and, as time permits, its relation to the question: "can you hear the shape of the drum?"
