On the Chern classes of singular complete intersections

Roberto Callejas-Bedregal, Michelle Morgado, Jose Seade

We consider two classical extensions for singular varieties of the usual Chern classes of complex manifolds, namely the total Schwartz-MacPherson and Fulton-Johnson classes, $c^{SM…

(FC)-Sequences, Mixed Multiplicities and Reductions of Modules

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

Let be a Noetherian local ring. In this work we use the notion of (FC)-sequences, as defined in \cite{perez-bedregal1}, to present some results concerning reduct…

Mixed multiplicities of arbitrary modules

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

Let be a Noetherian local ring. In this work we extend the notion of mixed multiplicities of modules, given in \cite{Kleiman-Thorup2} and \cite{Kirby-Rees1} (see…

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 parametrized by -finitely determined map germs. We prove that the constancy of t…

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

Let be a -dimensional Noetherian local ring and a finitely generated -submodule of a free module In this work we introduce a multiplicity sequen…

Rees's theorem for arbitrary ideals

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

This paper has been withdrawn by the authors, due a crucial error in the proof of the main theorem.
