On the poles of zeta functions for finite morphisms between normal surfaces
Edwin León-Cardenal, Jorge MartÃn-Morales, Willem Veys +1
For a divisor representing a function and another divisor representing a differential form on a normal surface singularity, there is a notion of motivic and topological zeta functi…
Modules of logarithmic derivations in weighted projective spaces and applications to free divisors
Jorge MartÃn-Morales, Wayne Ng Kwing King
We introduce a weighted version of the module of logarithmic derivations of a divisor in weighted projective space, and provide a generalization of Saito's criterion for freeness i…
An algorithm for annihilator and Bernstein-Sato polynomial of a rational function
Manuel González-Villa, Edwin León-Cardenal, Viktor Levandovskyy +1
The singularity theory of rational functions, i.e., the quotient of two polynomials, has been investigated in the past two decades. The Bernstein-Sato polynomial of a rational func…
Ordinary --tuples in cyclic quotient surface singularities
José I. Cogolludo-AgustÃn, Tamás Lászlo, Jorge MartÃn-Morales +1
We describe those Weil divisors of cyclic quotient surface singularities which are (abstract) --tuple curve singularities.
