In particular, the Cauchy problem for the abstract fractional hyperbolic equations in Banach spaces and fractional hyperbolic systems is studied. The behavior at infinity of the orbits of a uniformly stable semigroup which is not uniformly exponentially stable is investigated. Asymptotic expansions of solutions of parabolic equations in non-cylindrical domain near a cuspidal point are constructed. We study the one-dimensional Schrodinger operators with potentials being generalized functions of the first order. Extensions of quasidifferential operators are described in terms of boundary conditions. A theory of elliptic systems in Douglas-Nirenberg sense, based on the scale of Hilbert spaces with a function parameter is developed. The description of all Hilbert functional spaces which are interpolation for the couples of Sobolev Hilbert spaces is obtained.
