Half-isomorphisms whose inverses are also half-isomorphisms

Let $(G, *)$ and $(G^{'}, \cdot)$ be groupoids. A bijection $f : G \to G^{'}$ is called a half-isomorphism if $f (x * y) \in {f (x) \cdot f (y), f (y) \cdot f (x)}$ , for any $x, y \in G$ . A…

Half-automorphism group of Chein loops

Giliard Souza dos Anjos

A bijection $f$ of a loop $L$ is a half-automorphism if $f (x y) \in {f (x) f (y), f (y) f (x)}$ , for any $x, y \in L$ . A half-automorphism is nontrivial when it is neither an automorphism n…
