New Class of Exact Pp-Wave Solutions in Simple Supergravity

摘要

A class of exact solutions of the O(1) supergravity theory is presented. It is obtained from an ansatz motivated by a previously known exact plane-wave solution together with the additional assumption that the connection forms equal their torsion-free and zero-order Grassmann part. The demonstrated solutions are non-trivial and admit a covariantly constant spinor field. (Atomindex citation 14:769578)
