This paper deals with the existence of nontrivial doubly periodic solutions for the nonlinear telegraph equation where c ยฟ 0 is a constant, a; b โ C(R 2 ; R + ), f โ C(R 2 ร R + ; R + ), and a; b; f are 2 -periodic in t and x. We show the existence of positive doubly periodic weak solutions when 0
