Normal modes for massive spin 1 equation in Robertson-Walker space-time / A. Zecca. - In: INTERNATIONAL JOURNAL OF THEORETICAL PHYSICS. - ISSN 0020-7748. - 45:10(2006), pp. 1981-1987.
Abstract:
The general scheme of the massive spin-1 equation in curved space-time with associated conserved current is considered. A properly covariant scalar product between solutions of the spin-1 equation is defined in a standard way by means of the conservation of the current. The scheme is specialized to the Robertson-Walker space-time where solutions of the spin-1 equation have been previously determined. There results, in case of flat Robertson-Walker space-time, the automatic ortho-normalization property of the solutions, that therefore represent a set of normal modes.
