Abstract
The work is devoted to the study of the solvability of initial-boundary value problems for differential equations
(\(\Delta\) is the Laplace operator in space variables) with a non-negative function \(h(t)\). Similar equations are called pseudohyperbolic equations in the literature. The aim of the work is to prove the existence and uniqueness of regular solutions of the problems under study—solutions that have all S.L. Sobolev derivatives included in the equation.
