AB - We study a general parabolic initial-boundary-value problem for systems parabolic in Petrovskii’s sense with zero initialCauchy data in some anisotropic H¨ormander inner-product spaces.We prove that the operators corresponding to this problemare isomorphisms between the appropriate H¨ormander spaces. As an application of this result, we establish a theorem onthe local increase in regularity of solutions of the problem. We also obtain new sufficient conditions of continuity for thegeneralized partial derivatives of a given order of a chosen component of the solution.
