“…Lemma 4.2. ( [8]) Let X = {X(t), t ∈ R} be a centered stochastic process which satisfies the requirements of Theorem 2.1, T > 0, φ be a scaling function, ψ be the corresponding wavelet, S(y) = ψ(y), S φ (y) = φ(y); φ(y), u(t, λ), S(y), S φ (y) satisfy such conditions: the function u(t, y) is absolutely continuous with respect to y, the function φ(y) is absolutely continuous,…”
