定常Burgers方程的周期解

扫码查看
本文首先对Burgers方程的周期解关于粘性系数ε作幂级数展开,得到逼近函数之间的递推关系。然后,通过对逼近函数作Fourier级数展开,给出了逼近函数Fourier展开的通项形式,并证明了每个逼近函数的Fourier级数是一致且绝对收敛的。
Periodic solutions to the steady viscous Burgers equation
In this paper,the periodic solutions of the Burgers equation are expanded in a power series with respect to the viscosity coefficient ε which gives a recurrence relation among the approximate functions.Then,the general form of the Fourier expansions for the approximate functions are given by induction,and it is proved that the Fourier series of each approximate function is uniformly and absolutely convergent.
