A characterization of quasi-homogeneity in terms of liftable vector fields
Ignacio Breva Ribes, Raúl Oset Sinha
We prove under certain conditions that any stable unfolding of a quasi-homogeneous map-germ with finite singularity type is substantial. We then prove that if an equidimensional ma…

A note on 1-parameter stable unfoldings
Ignacio Breva Ribes, Raúl Oset Sinha
We give two characterisations of when a map-germ admits a 1-parameter stable unfolding, one related to the -codimension and another related to the normal form of a ve…
