in this paper we introduce the concept of topological number for locally convex topological spaces and prove some of its properties. it gives some criterions to study locally convex topological spaces in a discrete approach.

We review current research in the field of categorical quantum mechanics. We place the category of relations within the same categorical framework and point out the similarities with the category of Hilbert spaces. Subsequently, we provide a categorical model for investigating the spectral theorem (as provided in [22]), within the context of an internally diagonalisable element and apply these ...

Sense of place is the most important features of space for designers in relation between human and environment, although key theories of the mid-twentieth century have shown that some social and psychological factors are more effective than physical characteristics but in this research, the focus is on the physical features of space. Many researchers have been analyzed Physical features and its...
