This is the first of a series of papers systematically extending a 1+3 covariant and gaugeinvariant treatment of kinetic theory in curved space-times to a treatment of cosmic microwave background temperature anisotropies arising from inhomogeneities in the early universe. The present paper deals wit
The Cosmic Microwave Background (CMB) is taken today as reflecting the thermodynamical state of the universe at these early cosmic times. Based on this assumption and standard cosmological principles meanwhile many fundamental cosmological facts have been deduced from the CMB state which, however, t
The partition function for a free bosonic quantum field at local thermal equilibrium is calculated. The result is applied to a study of possible deviation from the Planck distribution of the cosmic microwave background radiation (CMB). We show that if the temperature is sufftciently smooth on short
