Wirsing’s theorem on approximating algebraic numbers by algebraic numbers of bounded degree is a generalization of Roth’s theorem in Diophantine approximation. We study variations of Wirsing’s theorem where the inequality in the theorem is strengthened,but one excludes a certain easily-described special set of approximating algebraic points.
