On the universal and generalized orbifold Euler characteristics
Sabir M. Gusein-Zade, Ignacio Luengo, Alejandro Melle-Hernández +1
We discuss the universal orbifold Euler characteristic and generalized orbifold Euler characteristics corresponding to finitely generated groups (the -Euler characteristics)…
Grothendieck ring of pairs of quasi-projective varieties
Sabir M. Gusein-Zade, Ignacio Luengo, Alejandro Melle-Hernández
We define a Grothendieck ring of pairs of complex quasi-projective varieties (that is a variety and a subvariety). We describe -structures and a power structure on/over this rin…
Generalized orbifold Euler characteristics on the Grothendieck ring of varieties with actions of finite groups
S. M. Gusein-Zade, I. Luengo, A. Melle-Hernández
The notion of the orbifold Euler characteristic came from physics at the end of 80's. There were defined higher order versions of the orbifold Euler characteristic and generalized…
On the -exponents of generic isolated plane curve singularities
E. Artal Bartolo, P. Cassou Noguès, I. Luengo +1
In 1982, Tamaki Yano proposed a conjecture predicting how is the set of -exponents of an irreducible plane curve singularity germ which is generic in its equisingularity class.…
The universal Euler characteristic of V-manifolds
S. M. Gusein-Zade, I. Luengo, A. Melle-Hernández
The Euler characteristic is the only additive topological invariant for spaces of certain sort, in particular, for manifolds with some finiteness properties. A generalization of th…
Bernstein polynomial of 2-Puiseux pairs irreducible plane curve singularities
E. Artal Bartolo, Pi. Cassou-Noguès, I. Luengo +1
In 1982, Tamaki Yano proposed a conjecture predicting the set of b-exponents of an irreducible plane curve singularity germ which is generic in its equisingularity class. In \cite{…
