Abstract

A loop Q is said to be left conjugacy closed if the set A = { L x / x Q } is closed under conjugation. Let Q be an LCC loop, let and be the left and right multiplication groups of Q respectively, and let I ( Q ) be its inner mapping group, M ( Q ) its multiplication group. By Drápal’s theorem [3, Theorem 2.8] there exists a homomorphism Λ : I ( Q ) determined by L x R x - 1 L x . In this short note we examine different possible extensions of this Λ and the uniqueness of these extensions.

AB - A loop $Q$ is said to be left conjugacy closed if the set $A=\lbrace L_x/x\in Q\rbrace $ is closed under conjugation. Let $Q$ be an LCC loop, let $\mathcal {L}$ and $\mathcal {R}$ be the left and right multiplication groups of $Q$ respectively, and let $I(Q)$ be its inner mapping group, $M(Q)$ its multiplication group. By Drápal’s theorem [3, Theorem 2.8] there exists a homomorphism $\Lambda : \mathcal {L} \rightarrow I(Q)$ determined by $L_x\rightarrow R^{-1}_x L_x$. In this short note we examine different possible extensions of this $\Lambda $ and the uniqueness of these extensions.
