Type-monotonicity conjecture for numerical semigroups
Type-monotonicity conjecture for numerical semigroups
Let denote the number of numerical semigroups of genus and type . Type-monotonicity conjecture. For each pair of integers satisfying ,
This is proposed as a type-refined analogue of the still-open conjecture that for every . Its general status is open.
