Smarandache Multi-Space Theory(IV)--Application to theoretical physics

Abstract

A Smarandache multi-space is a union of $n$ different spaces equipped with some different structures for an integer $n\geq 2$, which can be both used for discrete or connected spaces, particularly for geometries and spacetimes in theoretical physics. This is the 4th part of multi-spaces considering applications of multi-spaces to theoretical physics, including the relativity theory, the M-theory and the cosmology. Multi-space models for $p$-branes and cosmos are constructed and some questions in cosmology are clarified by multi-spaces.
