M. Sorg, IDENTITIES AND CONSERVATION-LAWS IN RELATIVISTIC SCHRODINGER-THEORY, Nuovo cimento della Societa italiana di fisica. B, Relativity, classical and statistical physics, 112(1), 1997, pp. 23-61
The theory of relativistic Schrodinger equations is further extended t
o include also non-conservation of the rest mass of a material system
due to particle creation (annihilation). The corresponding (non-)conse
rvation laws are discussed in detail, together with their close interr
elationship to the basic identities of the theory (--> Fierz, Bianchi,
and bundle identities). As a demonstration of the general theory, the
cosmological solutions of the Einstein-Yang-Mills-Higgs equations are
constructed over the Robertson-Walker universes.
