A numerical semigroup S is almost-positioned if for all \(s\in {{\mathbb {N}}}\backslash S\) we have that \(\mathrm{F}(S)+\mathrm{{m}}(S)+1-s\in S\). In this note we give algorithmics for computing the whole set of almost-positioned numerical semigroup with fixed multiplicity and Frobenius number. Moreover, we prove Wilf’s conjecture for this type of numerical semigroups.

几乎定位的数值半群

如果对于所有\ {s \ in {{\ mathbb {N}}} \反斜杠S \),我们都具有\(\ mathrm {F}(S)+ \ mathrm {{m} }(S)+ 1-s \ in S \)。在本说明中,我们给出了算法,用于计算具有固定多重性和Frobenius数的几乎定位的数值半群的整个集合。此外,我们证明了这类数字半群的威尔夫猜想。
