| Outline of Final Research Achievements |
A new general class of Lipschitz evolution operators in Banach spaces is introduced and a characterization of the continuous infinitesimal generators of such evolution operators is obtained. It is given a necessary and sufficient condition for the existence of a weakly continuously differentiable solution to an abstract Cauchy problem in Banach spaces. Nonlinear perturbations of a holomorphic semigroup of fractional growth is studied through investigation of the associated Cauchy problems. Studying discontinuous mappings on intervals satisfying certain assumptions, it is shown that for such mappings there exist periodic points of period. In a kinetic formulation, it is obtained a result of uniqueness and existence of the initial-bounary value problem for a scalar first-order conservation law with a multicative noise.
