The Bruce-Roberts Numbers of 1-Forms on an ICIS

Bárbara K. Lima-Pereira, Juan José Nuño-Ballesteros, Bruna Oréfice-Okamoto +1

We relate the Bruce-Roberts numbers of a 1-form with respect to an ICIS to other invariants as the GSV-index, Tjurina and Milnor numbers.

Disentangling mappings defined on ICIS

Alberto Fernández-Hernández, Juan J. Nuño-Ballesteros

We study germs of hypersurfaces that can be described as the image of -finite mappings defin…

On invariants of a map germ from n-space to 2n-space

Juan José Nuño-Ballesteros, Otoniel Nogueira da Silva, João Nivaldo Tomazella

We consider -finite map germs from to . First, we show that the number of double points that appears in a stabilization of…

Deformations of corank frontals

C. Muñoz-Cabello, J. J. Nuño-Ballesteros, R. Oset Sinha

We develop a Thom-Mather theory of frontals analogous to Ishikawa's theory of deformations of Legendrian singularities but at the frontal level, avoiding the use of the contact set…

A weak version of Mond's conjecture

R. Giménez Conejero, J. J. Nuño-Ballesteros

We prove that a map germ with isolated instability is stable if and only if , where is the image Milnor number define…

Liftable vector fields, unfoldings and augmentations

Juan José Nuño Ballesteros, Raúl Oset Sinha

We study liftable vector fields of smooth map-germs. We show how to obtain the module of liftable vector fields of any map-germ of finite singularity type from the module of liftab…
