A note on the distributions in quantum mechanical systems
Layth M. Alabdulsada
In this paper, we study the distributions and the affine distributions of the quantum mechanical system. Also, we discuss the controllability of the quantum mechanical system with…
Certain properties of contra-T*12-continuous functions
Hadi J. Mustafa, Layth M. Alabdulsada
The concept of contra function was introduced by Dontchev [2], in this work, we use the notion of T*12-open to study a new class of function called a contra-T*12-continuous functio…
On the divergence representation of the Gauss curvature of Riemannian surfaces and its applications
Cs. Vincze, M. Oláh, L. M. Alabdulsada
In the paper we consider Riemannian surfaces admitting a global expression of the Gauss curvature as the divergence of a vector field. It is equivalent to the existence of a metric…
On -Open Sets
Layth M. Alabdulsada
The aim of this paper is to define and study -open sets and related properties. A -open set is, roughly speaking, a generalization of a -open set, whic…
On the class of weakly almost contra-T*-continuous functions
Layth M. Alabdulsada
The aim of this paper is to introduce and investigate a new class of functions called weakly almost contra--continuity which is defined as a function from an operator topologi…
On non-positive curvature properties of the Hilbert metric
Layth M. Alabdulsada, László Kozma
In this paper, we consider different types of non-positive curvature properties of the Hilbert metric of a convex domain in R^n. First, we survey the relationships among the concep…
