Quasistochastic semigroup as a generalized group

Soviet Physics Journal, 1970
Two representations of the hyperbolic-tangent semigroup (HTS) are discussed: the group representation (the Lorentz group) and the semigroup representation (the quasistochastic semigroup of relativistic endomorphisms-QSRE). Through a generalization of the condition for regular conjugation, it is established that the QSRE is, in a certain sense, a ...

The Structure of Generalized Inverse Semigroups

Semigroup Forum, 2014
We prove that the structure of right generalized inverse semigroups is determined by free etale actions of inverse semigroups. This leads to a tensor product interpretation of Yamada's classical structure theorem for generalized inverse semigroups.

FINITARY POWER SEMIGROUPS OF INFINITE GROUPS ARE NOT FINITELY GENERATED

Bulletin of the London Mathematical Society, 2005
Summary: For a semigroup \(S\), the finitary power semigroup of \(S\), denoted \(P_f(S)\), consists of all finite subsets of \(S\) under the usual multiplication. The main result of this paper asserts that \(P_f(G)\) is not finitely generated for any infinite group \(G\).

Groups, Semigroups, and Generators

1979
Physical theories consist essentially of two elements, a kinematical structure describing the instantaneous states and observables of the system, and a dynamical rule describing the change of these states and observables with time. In the classical mechanics of point particles a state is represented by a point in a differentiable manifold and the ...

Semigroups generated by a group and an idempotent

Communications in Algebra, 1998
It is well known that the semigroup of all transformations on a finite set X of order n is generated by its group of units, the symmetric group, and any idempotent of rank n − 1. Similarly, the symmetric inverse semigroup on X is generated by its group of units and any idempotent of rank n − 1 while the analogous result is true for the semigroup of all
