摘要 研究一类非线性双曲方程 utt- M∫Ω| u| 2 dx△ u =| u| αu的初边值问题局部解的存在性和唯一性 .利用 Galerkin方法和改进的势井理论得到 :当 M(r)和α满足一定条件 ,且初值充分小时 。 We study the existence of local solutions of some nonlinear hyperbolic equation: u tt -M∫ Ω|u| 2 d x△u=|u| αu. By use of Galerkin′ method and modified potential well theory, we prove that if M(r) and α satisfy some conditions and initial value is small enough, then there exists a unique local solution.
