摘要:
In this paper, we consider the weakly damped wave equations with hereditary effects, and the nonlinearity f satisfies critical growth. The delay term g(t, u t ) may be driven by a function with very weak assumptions, namely, just measurability. We analyze the well-posedness of solutions and verify the existence of the pullback D-attractor in $${C_{H_0^1\left( \Omega \right)}} \times {C_{{L^2}\left( \Omega \right)}}$$ by constructing the energy functional and combining with the idea of the contractive function.
