Abstract

We prove the global well-posedness of weak solutions for nonlinear wave equations with supercritical source and damping terms on a three-dimensional torus T3\mathbb T^3 of the prototype \begin{align*} &u_{tt}-\Delta u+|u_t|^{m-1}u_t=|u|^{p-1}u, \;\; (x,t) \in \mathbb T^3 \times \mathbb R^+ ; \notag\\ &u(0)=u_0 \in H^1(\mathbb T^3)\cap L^{m+1}(\mathbb T^3), \;\; u_t(0)=u_1\in L^2(\mathbb T^3), \end{align*} where 1pmin{23m+53,m}1\leq p\leq \min\{ \frac{2}{3} m + \frac{5}{3} , m \}. Notably, pp is allowed to be larger than 66.
