What is Existence and general stabilization of the Timoshenko system with a thermo-viscoelastic damping and a delay term in the internal feedback about?

In this paper, we consider a Timoshenko system with a thermo-viscoelastic damping and a delay term in the internal feedback together with initial datum and boundary conditions of Dirichlet type, where g is a positive non-increasing relaxation function and {\mu}1, {\mu}2 are positive constants. Under an hypothesis between the weight of the delay term in the feedback and the the weight of the friction damping term, using the Faedo-Galerkin approximations together with some energy estimates, we prove the global existence of the solutions. Then, by introducing appropriate Lyapunov functionals, under the imposed constrain on the weights of the two feedbacks and the coefficients, we establish the general energy decay result from which the exponential and polynomial types of decay are only special cases.
