Research Abstract

M-theory is expected to be the unified theory and it has been analyzed vigorously in the world. M2 brane is one of the fundamental excitations in M-theory and we have analyzed how it looks like when the two-space dimensions are compactified on the 2-dim Tori. With the supermembrane action we have explicitly shown that the M2 brane can be a fundamental string, a D-string or their composite states in supersting according to the way of the wrapping on 2-dim Tori.
