Аннотация:
The generalized continuous random fields of second order with values in arbitrary complex normed space $X$ in the case when their
arguments belong to homogeneous space with compact transformation group $G$ are considered. Such fields are harmonizable in some
sense. The spectral representations of homogeneous random fields
in $X$ and $G$-invariant positive definite operator-valued kernels are
obtained. The special case of random fields with values in complex
Hilbert space and random fields on three-dimensional spheres are
also studied.
