Non-degenerate jump of Milnor numbers of surface singularities

Szymon Brzostowski, Tadeusz Krasiński, Justyna Walewska

Published 2015-08-11Version 1

The jump of the Milnor number of an isolated singularity f0 is the minimal non-zero difference between the Milnor numbers of f_0 and one of its deformations pfsq.We give a formula for the jump in some class of surface singularities in the case deformations are non-degenerate.
