Nonlinear SUSY Einstein-Hilbert-type action and unity of nature

Abstract:
In the previous confrernce we proposed a nonlinear SUSY invariant Einstein-Hilbert type action, "siperon-graviton model(SGM)" for spacetime and matter. In this conference after the quick review of SGM we discuss the linearization of SGM and nonlinear SUSY to obtain a equivalent linear SUSY theory, which is renormalizable. The Phenomenolgy and the cosmology of SGM may be added.
