Some combinatorial problems in the theory of partial transformation semigroups
Let \(X_n = \{1, 2, \ldots , n\}\). On a partial transformation \(\alpha : \mathop{\rm Dom}\nolimits \alpha \subseteq X_n \rightarrow \mbox{Im}\,\alpha \subseteq X_n\) of \(X_n\) the following parameters are defined: the breadth or width of \(\alpha\) is \(\mid{\mathop{\rm Dom}\nolimits}\ \alph...
