Abstract

A nonhomogeneous integro-differential equation of viscoelasticity with zero boundary conditions is studied. To facilitate the analysis, auxiliary functions are introduced, which enable the equation to be rewritten in a form suitable for rigorous investigation. The problem is subsequently reduced to a second-kind Volterra integral equation, which is solved using the Fourier method. A theorem establishing the uniqueness of the solution to the posed problem is also proven.
