Fibrations of tamely composable maps
Ying Chen, Cezar Joiţa, Mihai Tibăr
We study composed map germs with respect to their local fibrations. Under most general conditions, inspired by the tameness condition that was introduced recently, we prove the exi…
On singular maps with local fibration
Ying Chen, Mihai Tibăr
We discuss the most general condition under which a singular local tube fibration exists. We give an application to composition of map germs.
Fibrations structure and degree formulae for Milnor fibers
Nicolas Dutertre, Raimundo N. Araújo Dos Santos, Ying Chen +1
In this survey, we remind some fibrations structure theorems (also called Milnor's fibrations) recently proved in the real and complex case, in the local and global settings. We gi…
Invertible polynomial mappings via Newton non-degeneracy
Ying Chen, L. R. G. Dias, Kiyoshi Takeuchi +1
We prove a sufficient condition for the Jacobian problem in the setting of real, complex and mixed polynomial mappings. This follows from the study of the bifurcation locus of a ma…
On Newton non-degeneracy of polynomial mappings
Y. Chen, L. R. G. Dias, M. Tibar
We introduce a new non-degeneracy condition at infinity for a real or a mixed polynomial mapping which allows us to approximate its bifurcation locus in terms of certain Newton…
Singular open book structures from real mappings
Mihai Tibar, Ying Chen, Raimundo N. Araújo dos Santos
We prove extensions of Milnor's theorem for germs with nonisolated singularity and use them to find new classes of genuine real analytic mappings with positive dimensional sing…
