In this work, we will show that (Formula presented.) is a numerical semigroup whose Frobenius number belongs to (Formula presented.) and is a covariety. This fact allows us to present an algorithm which computes all the elements from (Formula presented.) We will prove that (Formula presented.) has multiplicity (Formula presented.) and is a ratio-covariety. As a consequence, we will show an algorithm which calculates all the elements belonging to (Formula presented.) Based on the above results, we will develop an interesting algorithm that calculates all numerical semigroups with a given multiplicity and complexity.}, publisher = {Multidisciplinary Digital Publishing Institute (MDPI)}, keywords = {algorithm}, keywords = {complexity}, keywords = {covariety}, keywords = {Frobenius number}, keywords = {multiplicity}, keywords = {ratio-covariety}, title = {The Set of Numerical Semigroups with Frobenius Number Belonging to a Fixed Interval}, doi = {10.3390/math13152538}, author = {Moreno Frías, María Ángeles and Rosales, Jose Carlos}, }
