On the frequency of height values

Abstract

We count algebraic numbers of fixed degree dd and fixed (absolute multiplicative Weil) height H\mathcal{H} with precisely kk conjugates that lie inside the open unit disk. We also count the number of values up to H\mathcal{H} that the height assumes on algebraic numbers of degree dd with precisely kk conjugates that lie inside the open unit disk. For both counts, we do not obtain an asymptotic, but only a rough order of growth, which arises from an asymptotic for the logarithm of the counting function; for the first count, even this rough order of growth exists only if k{0,d}k \in \{0,d\} or gcd(k,d)=1\gcd(k,d) = 1. We therefore study the behaviour in the case where 0<k<d0 < k < d and gcd(k,d)>1\gcd(k,d) > 1 in more detail. We also count integer polynomials of fixed degree and fixed Mahler measure with a fixed number of complex zeroes inside the open unit disk (counted with multiplicities) and study the dynamical behaviour of the height function.
