We construct a spectral sequence converging to the cohomology with compact support of
the m-th contact locus of a complex polynomial. The first page is explicitly described in terms …

In this work, we study a family of Cremona transformations of weighted projective planes
which generalize the standard Cremona transformation of the projective plane. Starting from …

In this paper, we extend the concept of Milnor fiber and Milnor number to curve germs on
surface quotient singularities. A generalization of the local δ-invariant is defined and …

This paper deals with the invariant R_X RX called the RR-correction term, which appears in
the Riemann–Roch and Numerical Adjunction Formulas for normal surface singularities …

We introduce the notion of bi-Lipschitz equivalence of ideals and derive numerical invariants
for such equivalence. In particular, we show that the log canonical threshold of ideals is a bi …

This article gives an explicit formula for the Ehrhart quasipolynomial of certain 2-dimensional
polyhedra in terms of invariants of surface quotient singularities. Also, a formula for the …

The main goal of this PhD thesis is the study of the cohomology ring of P2 w\R, being R a
reduced algebraic curve in the complex weighted projective plane P2 w whose irreducible …

This paper deals with cyclic covers of a large family of rational normal surfaces that can also
be described as quotients of a product, where the factors are cyclic covers of algebraic …

In this paper we present some applications of A'Campo-L\^ e's Theorem and we study some
relations between Zariski's Questions A and B. It is presented some classes of …
