Isomorphisms between semigroups of maps
2011Let X and Y be topological spaces and C and D semigroups under composition of maps from X to X and Y to Y respectively. Let H be an isomorphism from C to D; it is shown that if both C and D contain the constant maps then there exists a bijection h from X to Y such that H(f) = h∘f∘h⁻¹, VfɛC.

On the graphs of a ternary semigroup of mappings
Asian-European Journal of MathematicsLet [Formula: see text] and [Formula: see text] be two nonempty sets and [Formula: see text] and [Formula: see text] be the set of all functions from [Formula: see text] to [Formula: see text] and the set of all functions from [Formula: see text] to [Formula: see text], respectively. Then [Formula: see text] is a ternary semigroup of mappings under the

Markov Semigroups and Harmonic Maps
2003We present a semigroup approach to harmonic maps between metric spaces. Our basic assumption on the target space (N, d) is that it admits a ”barycenter contraction”, i.e. a contracting map which assigns to each probability measure q on N a point b(q) in N. This includes all metric spaces with globally nonpositive curvature in the sense of Alexandrov as

Generalized \(\Omega\)-semigroup mappings. I
1985Without being to explicit, an \(\Omega\)-semigroup consists of a multiplicative semigroup X and a set \(\Omega\) which is the union of n-ary operators (sums) on X except the semigroup operation itself \((n=0,1,2,...)\), where the operators in \(\Omega\) are connected with the semigroup operation.

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 ...
