Seifert forms and slice Euler characteristic of links
S. Yu. Orevkov, V. Florens
We define the Witt coindex of a link with non-trivial Alexander polynomial, as a concordance invariant from the Seifert form. We show that it provides an upper bound for the (local…
On complex line arrangements and their boundary manifolds
Vincent Florens, Benoît Guerville-Ballé, Miguel Marco Buzunariz
Let A be a line arrangement in the complex projective plane CP2. We define and describe the inclusion map of the boundary manifold --the boundary of a close regular neighborhood of…
Twisted Alexander polynomials of Plane Algebraic Curves
Jose Ignacio Cogolludo, Vincent Florens
We consider the Alexander polynomial of a plane algebraic curve twisted by a linear representation. We show that it divides the product of the polynomials of the singularity links,…
