An extension of the Wilf conjecture to semimodules over a numerical semigroup
Patricio Almirón, Julio José Moyano-Fernández
The aim of this paper is to propose an extension of the Wilf conjecture to semimodules over a numerical semigroup through a new approach toward the solution of the Wilf conjecture…
The 4/3 problem for germs of isolated plane curve singularities
Patricio Almirón
In this survey we overview the different approaches and solutions of a question posed by Dimca and Greuel about the quotient of the Milnor and Tjurina numbers.
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…
A note on a question of Dimca and Greuel
Patricio Almirón, Guillem Blanco
In this note we give a positive answer to a question of Dimca and Greuel about the quotient between the Milnor and Tjurina numbers of an isolated plane curve singularity in the cas…
