研究一类二维Newton—Boussinesq方程的周期初值问题,将方程转化为积分方程,用不动点原理得到解的局部存在性,用能量估计的方法证明经典解的整体存在性.
A class of periodic initial value problems for two-dimensional Newton-Boussinesq equations was investigated. First the Newton-Boussinesq equations were turned into the equivalent integral equations, then by the iteration methods the local existence of the solutions was obtained. Finally using the method of a priori estimates, the global existence of the solutions was proved.
