Abstract:

In this article, we investigate the following two problems Problem 1. Is finite-${C^0}{\text {-}}K$-determinacy a topological invariant among analytic map-germs? Problem 2. Do the topological types of all finitely-${C^0}{\text {-}}K$-determined map-germs have topological moduli, i.e. do they have infinitely many topological types with the cardinal number of continuum? Problem $1$ is solved affirmatively in the complex case. Problem $2$ is solved negatively in the complex case; and affirmatively in the real case.
