In this study, we give some results about the gaps, fundamental and special gaps of a pseudo symmetric numerical semigroup in the form of S=< 3, 3+ s, 3+ 2s> for s∈ Z+ and 3 s.

İlk olarak sayısal yarıgrup problemi, “ Sayısal yarıgruba ait olmayan en büyük tamsayıyı üreteçleri cinsinden nasıl ifade edilebilir?” şeklinde olup, 19. yy sonunda karşımıza çıkmıştır. Sayısal yarıgrup çalışan ilk ...

A subset S of N is called a numerical semigroup if S is closed under addition and S has element 0 and N\S is finite where N denotes the set of nonnegative integers. In this study, we are interested two subclass of maximal ...

In this study, we will give some results on Arf numerical semigroups of multiplicity four generated by {4, k, k + 1, k + 2} where k is an integer not less than 5 and k ≡ 1(mod 4).

In this study, we obtain an Arf semigroup by means of a sequence. We also establish some results on the Arf semigroup

In this study, we calculate the number of fundamental gaps of the some numerical semigroups which are for and and for and and or. Also, we give the type sequence of these numerical semigroups.

In this study, we will characterize the Arf numerical semigroup that is computed in a quotient of an Arf numerical semigroup by an positive integer. We will also obtain the one half of this special Arf numerical semigroup and ...
