Description of the research activity
The main activity of the members of this group is the study of factorization invariants in numerical and affine semigroups and their applications. The obtaining of algorithms for the computation of these parameters is one of the their main goals. These tasks not only remains in the theoretical study, but in most of the works are provided tools and implementations of the algorithms studied. Other lines and studies carried out by members of this group are the characterization of minimal presentations of related semigroups and the effective calculation of semigroup algebra invariants.
