Abstract
We consider a system of nonlinear Klein-Gordon equations in one space dimension with quadratic nonlinearities
(∂t2+∂x2+ mj2)uj = Nj(∂u),
j = 1, . . . , l. We show the existence of solutions in an analytic function space. When the nonlinearity satisfies a strong null condition introduced by Georgiev we prove the global existence and obtain the large time asymptotic behavior of small solutions.
