Abstract. The present paper is devoted to the derivation of an explicit form of linearly representable random fields in the form
where
,
is a Hilbert space, operators
are such that
and
where
.
The results obtained are the generalization of theorem proved in [3], [5], [7].
It is shown that a rank of nonstationary of field
depends
not only on a degree of non-self adjoint of
but on a degree of
nilpotency of commutator
.
In the present paper an explicit form of correlation function for discrete
spectrum of and
is derived. A form in the case of spectrum of operator
is constructed in zero and that of the operator
is pure discrete
of
and
is zero and the other is discrete, is obtained.
