Abstract
Assume that K +: H − → T − is a bounded operator, where H − and T − are Hilbert spaces and ρ is a measure on the space H −. Denote by ρK the image of the measure ρ under K +. We study the measure ρK under the assumption that ρ is the spectral measure of a Jacobi field and obtain a family of operators whose spectral measure is equal to ρK. We also obtain an analog of the Wiener-Itô decomposition for ρK. Finally, we illustrate the results obtained by explicit calculations carried out for the case, where ρK is a Lévy noise measure.
