Classification of simple 0-dimensional isolated complete intersection singularities
Thuy Huong Pham, Gerhard Pfister, Gert-Martin Greuel
The aim of this article is the classification of simple 0-dimensional isolated complete intersection singularities in positive characteristic. As usual, a singularity is called sim…
A note on finite determinacy of matrices
Thuy Huong Pham, Pedro Macias Marques
In this note, we give a necessary and sufficient condition for a matrix A in M to be finitely G-determined, where M is the ring of 2 x 2 matrices whose entries are formal power ser…
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…
On finite determinacy for matrices of power series
Gert-Martin Greuel, Thuy Huong Pham
Let be the ring of formal power series with maximal ideal over a field of arbitrary characteristic. On the ring of mat…
Mather-Yau Theorem in Positive Characteristic
Gert-Martin Greuel, Thuy Huong Pham
The well-known Mather-Yau theorem says that the isomorphism type of the local ring of an isolated complex hypersurface singularity is determined by its Tjurina algebra. It is also…
