On the convergence of solutions of regularized problem for motion equations of Jeffreys viscoelastic medium to solutions of the original problem

In this work, we consider initial-boundary-value problems for motion equations of viscoelastic medium with the Jeffreys constitutive law and for motion equations of the regularized Jeffreys model. We obtain a theorem on the convergence of weak solutions of initial-boundary-value problems for the regularized model to weak solutions of the original problem as the regularization parameter tends to zero.
