Karazin popup.description2 The object of research - commutative systems of non-selfadjoint nonbounded operators, statistically non-homogenous and non-stationary environments, non-stationary fields. The purpose of operation - investigation of commutative system of non-selfadjoint nonbounded operators. Description of the set of invariants for such systems of operators. Construction of models of statistically non-homogenous and non-stationary environments and investigation of wave propagation in such environments. Spectral analysis of non-stationary fields. Investigation of spectral properties of non-selfadjoint half-infinite operators. Methods of research - functional analysis, theory of functions and theory of differential operators. Main results - commutative system of non-selfadjoint nonbounded operators is investigated. Set of invariants for such systems is described. Models of statistically non-homogenous and non-stationary invariants are constructed and wave propagation in these environments is studied. Spectral properties of non-selfadjoint half-infinite operators are studied.
