Random Products in Semigroups of Mappings
1990A brief survey is given on some combinatorial aspects of finite full transformation semigroups, and counterparts for some of these results are derived for the semigroup of all order preserving mappings on a finite set.

The Wave Map of Feller Semigroups
2000The notion of wave map, inspired from Scattering Theory, was introduced in [7] within the framework of Quantum Dynamical Semigroups. The current article is addressed to classical probabilists, building up the wave map for two (classical) Feller semigroups which are recurrent in the sense of Harris and obtaining an interesting relationship with the ...

Rank Properties in Semigroups of Mappings
1987The rank of a finite semigroup S is defined as r(S) = min{|A|: ‹A› = S}. If S is generated by its set E of idempotents or by its set N of nilpotents, then the idempotent rank ir(S) and the nilpotent rank nr(S) are given by ir(S) = min{|A|:A ⊆ E and ‹A› = S} and nr(S) = min{|A|:A ⊆ n and ‹A› = S} respectively; these are potentially different from r(S ...
