Abstract

In this paper, we consider a mixed nonlocal problem for a wave equation with the Dirichlet condition at x = 1 and a nonlocal boundary condition at x = 0 of integral forms. First, we establish two local existence theorems by using Faedo–Galerkin method. Next, we give a sufficient condition to guarantee the global existence and exponential decay of weak solutions.
