On Isolated Gaps of Numerical Semigroups of embedding dimension two

Shubh N. Singh, Ranjan K. Ram

We explicitly describe all the isolated gaps of any numerical semigroup of embedding dimension two, and we give an exact formula for the number of isolated gaps of these numerical…

Semigroups of transformations whose characters belong to a given semigroup

Mosarof Sarkar, Shubh N. Singh

Let $X$ be a nonempty set and $P = {X_{i} : i \in I}$ a partition of $X$ . Denote by $T (X)$ the full transformation semigroup on $X$ , and $T (X, P)$ the subsemig…

Semigroups of (linear) transformations whose restrictions belong to a given semigroup

Mosarof Sarkar, Shubh N. Singh

Let $T (X)$ (resp. L(V)) be the semigroup of all transformations (resp. linear transformations) of a set $X$ (resp. vector space $V$ ). For a subset $Y$ of $X$ and a subsemigroup $\m…

$L$ -Primitive Words in Submonoids

Shubh Narayan Singh, K. V. Krishna

This work considers a natural generalization of primitivity with respect to a language. Given a language $L$ , a nonempty word $w$ is said to be $L$ -primitive if $w$ is not a proper…
