These semigroups are defined by modular Diophantine inequalities and they are a generalization of proportionally modular numerical semigroups. We give an algorithm to compute their minimal generating sets, and we specialize when p = 2. For this case, we also provide a faster algorithm to compute their minimal system of generators, prove they are Cohen–Macaulay and Buchsbaum, and determinate their (minimal) Frobenius vectors. Besides, Gorenstein proportionally modular affine semigroups are characterized.}, publisher = {World Scientific}, keywords = {Affine semigroup}, keywords = {Buchsbaum ring}, keywords = {Cohen–Macaulay ring}, keywords = {Frobenius vector}, keywords = {Gorenstein ring}, keywords = {modular Diophantine inequalities}, keywords = {numerical monoid}, keywords = {numerical semigroup}, title = {Proportionally modular affine semigroups}, doi = {10.1142/S0219498818500172}, author = {García García, Juan Ignacio and Moreno Frías, María Ángeles and Vigneron Tenorio, Alberto}, }
