Let G be PSΒΈL(q), PSΒΊ L (q), Sp L (q) or PSp L (q), where q is a power of the prime p. Using results on the numbers of special squarefree polynomials over finite fields, we describe and count the conjugacy classes of p-elements with abelian centralizers in G. Similar results are obtained for the sem
