Beyond Regular Semigroups [PDF]

open access: yes, 2012
The topic of this thesis is the class of weakly U-abundant semigroups. This class is very wide, containing inverse, orthodox, regular, ample, adequate, quasi-adequate, concordant, abundant, restriction, Ehresmann and weakly abundant semigroups.

Convolution semigroups of states. [PDF]

open access: yes, 2011
Convolution semigroups of states on a quantum group form the natural noncommutative analogue of convolution semigroups of probability measures on a locally compact group.

DIVISIBILITY TESTS FOR SMARANDACHE SEMIGROUPS [PDF]

open access: yes, 2002
Two Divisibility Tests for Smarandache semigroups are given. Further, the notion of divisibility of elements in a semigroup is applied to characterize the Smarandache semigroups.

Right simple subsemigroups and right subgroups of compact convergence semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
Clifford and Preston (1961) showed several important characterizations of right groups. It was shown in Roy and So (1998) that, among topological semigroups, compact right simple or left cancellative semigroups are in fact right groups, and the closure ...

A photon transport problem with a time-dependent point source [PDF]

open access: yes, 2009
We consider a time-dependent problem of photon transport in an interstellar cloud with a point photon source modeled by a Dirac δ functional. The existence of a unique distributional solution to this problem is established by using the theory of ...

The Concentration Function Problem for Locally Compact Groups Revisited: Nondissipating Space-Time Random Walks, -Decomposable Laws, and Their Continuous Time Analogues

open access: yesJournal of Mathematics, 2013
The concentration function problem for locally compact groups is concerned with the structure of groups admitting adapted nondissipating random walks.

Cayley automaton semigroups [PDF]

open access: yes, 2015
Let S be a semigroup, C(S) the automaton constructed from the right Cayley graph of S with respect to all of S as the generating set and ∑(C(S)) the automaton semigroup constructed from C(S). Such semigroups are termed Cayley automaton semigroups. For
