Abstract
The Goeritz matrix of a connected link diagram is diagonalized to a normal form by the elementary divisor theory. The integer sequence given by the diagonal entries of this form is a link invariant called the Georitz invariant. In this paper, we study the Goeritz invariants of pretzel links.
