Topological Triviality of Families of Singular Surfaces

R. Callejas-Bedregal, K. Houston, M. A. S. Ruas

We study the topological triviality of families of singular surfaces in $C^{3}$ parametrized by $A$ -finitely determined map germs. We prove that the constancy of t…

A numerical characterization of reduction for arbitrary modules

R. Callejas-Bedregal, V. H. Jorge Perez

Let $(R, m)$ be a $d$ -dimensional Noetherian local ring and $E$ a finitely generated $R$ -submodule of a free module $R^{p} .$ In this work we introduce a multiplicity sequen…
