THEORY OF GRAVITATION AND ELECTROMAGNETISM

Abstract : A rederivation of the Rainich theory by use of four-component spinors, a spinor classification of empty space-times, a study of static cylindrically symmetric solutions of the Rainich equations, and investigations concerning the initial value problem are presented. Also included was an attempt to write a set of equations involving only geometric quantities which would be equivalent to the gravitational-neutrino equations and a study of the gravitational field of a fastmoving mass. The imcompleteness of the Rainich theory as a physical theory is discussed and the implifications for future work is given. (Author)
