This paper deals with the existence of nontrivial doubly periodic solutions for the nonlinear telegraph equation where c ΒΏ 0 is a constant, a; b ∈ C(R 2 ; R + ), f ∈ C(R 2 Γ— 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
