Abstract

In this article, we provide estimates for the degree of V-bilipschitz determinacy of weighted homogeneous function germs defined on
weighted homogeneous analytic variety V satisfying a convenient Lojasiewicz condition.The result gives an explicit order such that the geometrical structure of a weighted homogeneous polynomial function germs is preserved after higher order perturbations.
