FUZZY SEMIGROUPS IN REDUCTIVE SEMIGROUPS [PDF]
Korean Journal of Mathematics, 2013 We consider a fuzzy semigroup $S$ in a right (or left) reductive semigroup $X$ such that $S(k)=1$ for some $k \in X$ and find a faithful representation (or anti-representation) of $S$ by transformations of $S$. Also we show that a fuzzy semigroup $S$ in a weakly reductive semigroup $X$ such that $S(k)=1$ for some $k \in X$ is isomorphic to the ...

Pi Semigroup Algebras of Linear Semigroups [PDF]
Proceedings of the American Mathematical Society, 1990 It is well-known that if a semigroup algebra K [ S ] K[S] over a field K K satisfies a polynomial identity then the semigroup S S has the permutation property. The converse is not true in general even when S S is a group.

Regularity and separation for Grušin‐type p‐Laplace operators
Mathematische Nachrichten, EarlyView.Abstract We analyze p‐Laplace type operators with degenerate elliptic coefficients. This investigation includes Grušin‐type p‐Laplace operators. We describe a separation phenomenon in elliptic and parabolic p‐Laplace type equations, which provide an illuminating illustration of simple jump discontinuities of the corresponding weak solutions ...

Neutrosophic LA-Semigroup Rings [PDF]
Neutrosophic Sets and Systems, 2015 Neutrosophic LA-semigroup is a midway structure between a neutrosophic groupoid and a commutative neutrosophic semigroup. Rings are the old concept in algebraic structures.

Difference of composition operators on weighted Bergman spaces over the half-plane
Journal of Inequalities and Applications, 2016 Recently, the bounded, compact and Hilbert-Schmidt difference of composition operators on the Bergman spaces over the half-plane are characterized in (Choe et al. in Trans. Am. Math. Soc., 2016, in press).

Congruences and group congruences on a semigroup
, 2013 We show that there is an inclusion-preserving bijection between the set of all normal subsemigroups of a semigroup S and the set of all group congruences on S. We describe also group congruences on E-inversive (E-)semigroups. In particular, we generalize

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This paper shows that long‐term stability and blowing‐up solutions for a nonlinear wave equation with a nonlocal damping of Choi and MacCamy type and a nonlocal dispersion can occur. The method of proof of general decay relies on a suitable Lyapunov functional.

International Journal of Mathematics and Mathematical Sciences, 2002 Let R be a ring. The circle operation is the operation a∘b=a+b−ab, for all a,b∈R. This operation gives rise to a semigroup called the adjoint semigroup or circle semigroup of R. We investigate rings in which the adjoint semigroup is regular. Examples are

Some ordered matrix semigroups [PDF]
arXiv, 2023 A semigroup together with compatible partial order is called an odered semigroup. In this paper we discuss the ordered matrix semigroups.

Friedlander's eigenvalue inequalities and the Dirichlet-to-Neumann semigroup
, 2012 If $\Omega$ is any compact Lipschitz domain, possibly in a Riemannian manifold, with boundary $\Gamma = \partial \Omega$, the Dirichlet-to-Neumann operator $\mathcal{D}_\lambda$ is defined on $L^2(\Gamma)$ for any real $\lambda$.
