Tame deformations of highly singular function germs

Cezar Joiţa, Matteo Stockinger, Mihai Tibăr

We give analytic and algebraic conditions under which a deformation of real analytic functions with non-isolated singular locus is a deformation with fibre constancy.

Atypical points at infinity and algorithmic detection of the bifurcation locus of real polynomials

Luis Renato G. Dias, Cezar Joiţa, Mihai Tibăr

We show that the variation of the topology at infinity of a two-variable polynomial function is localisable at a finite number of "atypical points" at infinity. We construct an eff…

Bifurcation set of multi-parameter families of complex curves

Cezar Joita, Mihai Tibar

The problem of detecting the bifurcation set of polynomial mappings , , , has been solved in the case , only. Its s…

Bifurcation values of families of real curves

Cezar Joita, Mihai Tibar

In more than two variables, detection of the bifurcation set of polynomial mapping $\bR^n \to \bR^p$, , is a still unsolved problem. In this note we provide a solution for…

Convexity properties of coverings of 1-convex surfaces

Mihnea Colţoiu, Cezar Joiţa

We prove that there exists a 1-convex surface whose universal covering does not satisfy the discrete disk property.

The disk property of coverings of 1-convex surfaces

M. Colţoiu, C. Joiţa

Let be an 1-convex surface and an (unbranched) covering map. We prove that if does not contain an infinite Nori string of rational curves then $\ti…
