Algorithms for group actions in arbitrary characteristic and a problem in singularity theory
Gert-Martin Greuel, Thuy Huong Pham
We consider the actions of different groups G on the space M of m x n matrices with entries in the formal power series ring K[[x1,..., xs]], K an arbitrary field. G acts on M by an…

Finite determinacy of matrices and ideals
Gert-Martin Greuel, Thuy Huong Pham
The main aim of this paper is to characterize ideals I in the power series ring R=K[[x1,...,xs]] that are finitely determined up to contact equivalence by proving that this is the…
