RT journal article T1 Generalized Strongly Increasing Semigroups A1 García Barroso, E.R. A1 García García, Juan Ignacio A1 Vigneron Tenorio, Alberto A2 Matemáticas K1 generalized strongly increasing semigroup K1 strongly increasing semigroup K1 Frobenius number K1 Apéry set K1 singular analytic plane curve AB In this work, we present a new class of numerical semigroups called GSI-semigroups. We see the relations between them and other families of semigroups and we explicitly give their set of gaps. Moreover, an algorithm to obtain all the GSI-semigroups up to a given Frobenius number is provided and the realization of positive integers as Frobenius numbers of GSI-semigroups is studied.
