The aim of this paper is devoted to introduce and study the concepts of semi-compact (resp.semi-Lindelӧf, locally semi-compact) spaces in a neutrosophic crisp topological space. Several properties, functions properties of neutrosophic crisp semi-compact spaces are studied. In addition to these, we introduce and study the definition of neutrosophic crisp semi-Lindelӧf spaces and neutrosophic crisp locally semi-compact spaces. We show that neutrosophic crisp semi-compact spaces is preserved under neutrosophic crisp irresolute function and neutrosophic crisp pre-semi-closed function with neutrosophic crisp semi-compact point inverses.

Can I Embed the Mass/Energy into the Spacetime Structure?

Authors: Mirosław J. Kubiak
Comments: 4 Pages.

Some physicists believe that the spacetime, in absence of the matter, is empty. In this paper I presented an opposing point of view.
