. We study the Cauchy problem for the nonlinear Klein-Gordon equation with a cubic convolution{Vr*(w(t))2}w(t),where Vr(x)=|x|(cid:631)r,in (x, t)^RnXR. We prove the existence of weak solutionsfor 0<y<n. We also prove thatfor 0<7"<Min{4, n) the weak solutionis unique and there existsa regular solution.
