Topology of real Milnor fibration for non-isolated singularities
Nicolas Dutertre, Raimundo N. Araújo Dos Santos
We consider a real analytic map , , that satisfies Milnor's conditions (a) and (b) introduced by D…
Lipschitz geometry of complex surfaces: analytic invariants and equisingularity
Walter D. Neumann, Anne Pichon
We prove that the outer Lipschitz geometry of a germ of a normal complex surface singularity determines a large amount of its analytic structure. In particular, it follows…
An explicit expression of the Luroth invariant
Romain Basson, Reynald Lercier, Christophe Ritzenthaler +1
In this short note, we give an algorithm to get an explicit expression of the Luroth invariant in terms of the Dixmier-Ohno invariants. We also get the explicit factorized expressi…
A wall crossing formula for degrees of real central projections
Christian Okonek, Andrei Teleman
The main result is a wall crossing formula for central projections defined on submanifolds of a real projective space. Our formula gives the jump of the degree of such a projection…
