Combinatorial results for order-preserving partial injective contraction mappings

Bayo Musa Ahmed, Nadia Aldhamri, Fatma Al-Kharousi +2

Let $I_{n}$ be the symmetric inverse semigroup on $X_{n} = {1, 2, \dots, n}$ . Let $O C I_{n}$ be the subsemigroup of $I_{n}$ consisting of all order-preser…

Operadic approach to HNN-extensions of Leibniz algebras

Georg Klein, Chia Zargeh

We construct HNN-extensions of Lie di-algebras in the variety of di-algebras and provide a presentation for the replicated HNN-extension of a Lie di-algebras. Then, by applying the…
