Abstract
We analyze some dynamical issues in a modified type IIA supergravity, recently proposed as an extension of M theory that admits de Sitter space. In particular we find that this theory has multiple zero-brane solutions. This suggests a microscopic quantum mechanical matrix description which yields a massive deformation of the usual M(atrix) formulation of M theory and type IIA string theory.Keywords
