On certain semigroups of finite oriented and order-decreasing partial transformations

Gonca Ayık, Hayrullah Ayık, Ilinka Dimitrova +1

Let $P O RD_{n}$ be the semigroup consisting of all oriented and order-decreasing partial transformations on the finite chain $X_{n} = {1 < \dots < n}$ . Let $\mathcal{IORD}_…

On certain subsemigroups of finite oriented and order-decreasing full transformations

Gonca Ayık, Hayrullah Ayık, Ilinka Dimitrova +1

Let $O RD_{n}$ be the semigroup consisting of all oriented and order-decreasing full transformations on the finite chain $X_{n} = {1 < \dots < n}$ , and for $1\leq r\leq n-1…

On certain semigroups of finite monotone and order-decreasing partial transformations

Gonca Ayık, Hayrullah Ayık, Ilinka Dimitrova +1

Let $P M D_{n}$ be the semigroup consisting of all monotone and order-decreasing partial transformations, and let $I M D_{n}$ be the subsemigroup of $\mathcal{PMD}_…
