The minimal Tjurina number of irreducible germs of plane curve singularities
Maria Alberich-Carramiñana, Patricio Almirón, Guillem Blanco +1
In this paper we give a positive answer to a question of Dimca and Greuel about the quotient between the Milnor and the Tjurina numbers for any irreducible germ of plane curve sing…
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.…
Higher order generalized Euler characteristics and generating series
S. M. Gusein-Zade, I. Luengo, A. Melle-Hernández
For a complex quasi-projective manifold with a finite group action, we define higher order generalized Euler characteristics with values in the Grothendieck ring of complex quasi-p…
