研究一类非线性双曲方程的初边值问题{utt-m‖△↓u‖2^2)△u-r△ut=β|u|^αu, u|t=0=u0(x),ut|t=0=u1x, u|δΩ=0,得到了问题整体强解的存在性,并在一定条件下,研究了解的爆破现象.
The following nonlinear hyperbolic equation is discussed utt-m‖△↓u‖2^2)△u-r△ut=β|u|^αu with the initial-boundary value problem.The condition of existence and nonexistence for the global solution is given.
