Cezar Joiţa, Mihai Tibăr
We show the existence of polynomial maps which have a regular bifurcation value, while over a neighbourhood of this value the fibres are connected and diffeomorphic.

Euclidean distance discriminants and Morse attractors
Cezar Joiţa, Dirk Siersma, Mihai Tibăr
Our study concerns the Euclidean distance function in case of complex plane curves. We decompose the ED discriminant into components which are responsible for three types of behavi…
