Abstract
A cosmological scenario of a light axino and a lighter gravitino is presented. The most important consequence is that it can mimick the mixed dark matter (MDM) model of the large scale structure formation. The presence of axino and gravitino is inevitable in supergravity extension of the invisible axion solution of the strong CP problem. The possibility of a light gravitino is popular in the recent efforts of gauge mediated supersymmetry breaking.
