摘要

We investigate the problem with inhomogeneous integral condition for a homogeneous partial differen tial equation of the first order with respect to time and, in the general case, of infinite order with respect to the space variable with constant coefficients. We prove the existence and uniqueness of a solution of the problem in a class of quasipolynomials of the special form. We construct a solution of this problem with the use of the differential-symbol method. In the case of existence of a nonunique solution of the problem, we propose formulas for the construction of a particular solution of the problem.
