“…In this work, we want to focus on the theory of heat conduction called Moore‐Gibson‐Thompson. It is worth recalling that this theory has received much attention in the last four years [
10–24] since many authors have investigated the qualitative and quantitative properties of the solutions to this equation. If we consider the type III heat conduction theory proposed by Green‐Naghdi [6], we can see that it is based on the constitutive equation in the case of centrosymmetric materials:
where
is the heat flux vector, θ is the temperature and α is the thermal displacement.…”
