Invariant subspaces of translation semigroups [PDF]
, 2005 In these lectures I shall give an account of some recent results and open problems relating to subspaces of square integrable functions on the real line which are jointly invariant for a pair of semigroups of unitary operators. These semigroups are quite

Regular, Commutative, Maximal Semigroups of Quotients
, 1975 A well-known theorem which goes back to R. E. Johnson [4], asserts that if R is a ring then Q(R), its maximal ring of quotients is regular (in the sense of v. Neumann) if and only if the singular ideal of R vanishes. In the theory of semigroups a natural

The dynamical Cuntz semigroup and ideal-free quotients of Cuntz semigroups [PDF]
We develop a theory of general quotients for W- and Cu-semigroups beyond the case of quotients by ideals. To this end, we introduce the notion of a normal pair, which allows us to take quotients of W-semigroups in a similar way as normal subgroups arise ...

Some Types of Ideals on KS-Semigroups
, 2014 In this paper we introduce a new types of ideals in KS- Semigroups in ordinary and fuzzy sense,we called it KS-H- ideal and fuzzy KS-H-ideal and study its properties The notation of BCK algebra introduced by Y.Imai and K.Ise'ki [3] in 1966.

Automorphisms and range families of transformation semigroups [PDF]
, 1984 The problem of describing all automorphisms of a given semigroup of transformations of a set X has interested a number of mathematicians in the past fifty years. J. Schreier showed that all automorphisms of the full transformation semigroup T“ are inner,

Fuzzy right, left, quasi-ideals, bi-ideals in ordered semigroups
, 2009 In this paper we give some equivalent definitions of fuzzy right (left) ideals and fuzzy bi-ideals which are useful for applications. In fact, they show how similar is the theory of ordered semigroups based on fuzzy ideals with the theory of ordered ...
