Abstract:
We develop a method for calculating vacuum expectation values of the energy–momentum tensor of a scalar field on homogeneous spaces with an invariant metric. Solving this problem involves the method of generalized harmonic analysis based on the method of coadjoint orbits.
Keywords:
vacuum polarization, energy–momentum tensor, harmonic analysis on homogeneous spaces.
