The Global Solution of a Damped Boussinesq Equation with Initial Boundary Conditions
【摘要】 运用Fourier变换和扰动方法研究了一类阻尼Boussinesq方程初边值问题的整体解.在一定条件下得到了这类Boussinesq方程在古典空间中整体解的存在唯一性和形式解的长时间渐近性.
【Abstract】 Making use of Fourier transformation and perturbation method,this paper deals with the global solution of initial boundary problem for a damped Boussinesq equation.Under certain assumptions,the existence and uniqueness of the global solution to the Boussinesq equation are established in a classical space.The long time asymptotic behavior of the formal approximation solution is discussed in detail.
