On automorphisms of transformation semigroups [PDF]

, 1993
This paper addresses the problem of describing automorphisms of semigroups of transformations. In [2] we were involved in characterizing all automorphisms of CroisotTeissier semigroups. The semigroups of transformations that belong to this large family

Spectral convolution of star-like transformation semigroups for modeling telecommunication signal strength and user experience in Gombe state, Nigeria

Journal of Nigerian Society of Physical Sciences
An efficient and mathematically sound method for simulating the distributions of telecommunication signals is the star-like semigroup convolution model. A rigorous operator-theoretic measure of signal strength is provided by the (S3I), which is obtained ...

Minimal congruences on finite transformation semigroups of weak Y-stabilizer(有限弱Y-稳定变换半群的极小同余)

Zhejiang Daxue xuebao. Lixue ban, 2011
设T(X)为有限集X上的全变换半群，Y为X的任意非空子集，引入有限弱Y-稳定变换半群W(Y) = {α∈T(X): Yα⊆Y}，证明了当W(Y)满足1< |Y| < |X|时，W(Y)有且仅有2个极小同余.另外，当|Y| =|X|（即Y=X或1= |Y|

Infinite transformation semigroups [PDF]

, 2018
In this thesis some topics in the field of Infinite Transformation Semigroups are investigated. In 1966 Howie considered the full transformation semigroup (x) on an infinite set x of cardinality m.

Convergence of Implicit Iterative Processes for Semigroups of Nonlinear Operators Acting in Regular Modular Spaces

Mathematics
This paper focuses on one-parameter semigroups of ρ-nonexpansive mappings Tt:C→C, where C is a subset of a modular space Xρ, the parameter t ranges over [0,+∞), and ρ is a convex modular with the Fatou property. The common fixed points of such semigroups
