摘要:In this paper, we study (m,n)-ideals of an LA -semigroup in detail. We characterize (0,2)-ideals of an LA -semigroup S and prove that A is a (0,2)-ideal of S if and only if A is a left ideal of some left ideal of S. We also show that an LA -semigroup S is 0-(0,2)-bisimple if...

摘要:In this paper, we introduce tensor product C-semigroups of operators on Banach spaces. The basic properties are presented. The generator and the resolvent of the generator of such semigroups are studied. The compactness of tensor productC-semigroups is also discussed.

摘要:We consider the ternary semigroup S of the fuzzy points of a ternary semigroup S, and discuss the relation between some fuzzy ideals of a ternary semigroup S and the subsets of S .

摘要:We prove that every π-regular semigroup such that all its elements are divided by one another on the left in potential sense, is a right group.

摘要:In this paper, using δ- strongly monotone and λ- strictly pseudo-contractive (in the terminology of Browder-Petryshyn type) mapping F on a real Hilbert space H, we introduce an implicit iterative scheme to find a common element of the set of solutions of a system of equilibr...

摘要:A flexible Euler-Bernoulli beam formulated by partial differential equations subject to the boundary shear force feedback is investigated in this paper. First, an abstract evolution equation corresponding to the beam system is established in an appropriate Hilbert space. Then, a ...

摘要:It is proved that if (S,∗) is a proper *-semigroup and if D is 0-characteristic integral domain then (D[S],∗) is nil-semisimple provided that S is finite or i ∈ D.Let (S,∗) be a finite proper *-semigroup and F be a finite field of characteristic p such that (F[S],∗...

摘要:In this paper, we introduce the notions of l,r ((r,l))-derivations of a QS-algebras, (r,l) ((l,r))- t - derivations of a QS-algebras, t- bi- derivations of a QS-algebras and we investigate several interesting basic properties.

摘要:In this paper, we characterized the Green’s relation on ; the contraction mapping injective partial transformation semigroup on n-objects. Using two parameters. We found that the order of L-classes and are the same but is different.

摘要:In this paper we consider the semigroups of quasi-open transformations. A map f between topological spaces X and Y is quasi-open if for any non-empty open set U ⊂ X, the interior of f (U) in Y is non-empty. We give abstract characterizations of semigroups of continuous quasi...
