Metric properties of semialgebraic mappings
Krzysztof Kurdyka, Stanisław Spodzieja, Anna Szlachcińska
We give an effective estimation from above for the local Łojasiewicz exponent for separation of semialgebraic sets and for a semialgebraic mapping on a closed semialgebraic set. We…
Irrational mixed decomposition and sharp fewnomial bounds for tropical polynomial systems
Frédéric Bihan
Given convex polytopes in and finite subsets of the Minkowsky sums , we consider the quantity $N(W)=\sum_{I \subset {\bf [}r {\bf…
Semisimple quantum cohomology of some Fano varieties
Nicolas Perrin
We give sufficient conditions for the semisimplicity of quantum cohomology of Fano varieties of Picard rank 1. We apply these techniques to prove new semisimplicity results for som…
Distance to the discriminant
Christophe Raffalli
We will study algebraic hyper-surfaces on the real unit sphere given by an homogeneous polynomial of degree d in n variables with the view point, rarely exploite…
