Inverse semigroups generated by nilpotent transformations
Let $X$ be a set with infinite cardinality $m$ and let $B$ be the Baer-Levi semigroup, consisting of all one-one mappings $a:X\rightarrow X$ for which $∣X\Xα∣ = m$. Let $K_m=<B^{-1}B>$, the inverse subsemigroup of the symmetric inverse semigroup $\mathcal T(X)$ generated by all products $\beta...
