Combinatorial results for order-preserving partial injective contraction mappings
Bayo Musa Ahmed, Nadia Aldhamri, Fatma Al-Kharousi +2
Let be the symmetric inverse semigroup on . Let be the subsemigroup of 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…
A note on identities in plactic monoids and monoids of upper-triangular tropical matrices
Alan J. Cain, Georg Klein, Łukasz Kubat +2
This paper uses the combinatorics of Young tableaux to prove the plactic monoid of infinite rank does not satisfy a non-trivial identity, by showing that the plactic monoid of rank…
