Karazin popup.description2 Investigation object - evolution equations in Banach and Hilbert spaces, in particular, implicit neutral differential delay equations, semilinear differential operator equations with nonstationary linear part. Work purpose - to obtain existence and uniqueness theorems, to construct solutions of exponential and overexponential growth, to describe a set of initial functions. Investigation methods - the spectral theory of non-self-adjoint operators and operator sheaves, the contractive mapping method, the theory of integral equations, the Laplace transform method in a Banach space.
