Abstract:

Let $G$ be a finite group with identity $e$, and let $f$ be a permutation of $G$ of
order $n$. We say that $f$ is a skew-morphism of
$G$ if $f(e)=e$, and there exists a function $\pi$ from $G$ to the set $\{0,…,n-1\}$
such that $f(xy)=f(x)f^{\pi(x)}(y)$ for all $x,y$ in $G$.
In the lecture we study the basic properties of skew-morphisms of cyclic groups.
