Abstract: | The authors consider the well-posedness in energy space of the critical non-linear system of wave equations with Hamiltonian structure where there exists a function F(λ, μ) such that By showing that the energy and dilation identities hold for weak solution under some assumptions on the non-linearities, we prove the global well-posedness in energy space by a similar argument to that for global regularity as shown in “Shatah and Struwe’s paper, Ann. of Math. 138, 503–518 (1993)”.
