Abstract

We investigate Cauchy problem to double dispersion equations with polynomial type nonlinearities with variable coefficients. Necessary and sufficient conditions for nonexistence of global weak solutions and nonblowing up ones are found for subcritical initial energy. For supercritical energy a sufficient condition for finite time blow up of the weak solutions, independent of the scalar product of the initial data, is developed.

具有线性恢复力和变系数非线性的双色散方程全局解的不存在性

研究了具有变系数多项式型非线性的双色散方程的Cauchy问题。得到了亚临界初始能量不存在整体弱解和不爆破解的充分必要条件。对于超临界能量，给出了与初始数据的标量积无关的弱解的有限时间爆破的充分条件。
