在函数类空间:W={u(x)=[sin f(r)eidθ,cos f(r)]∈H1(B,S2);u|坠B=g}中,研究Landau-Lifshitz型泛函Eε(u,B)=1/2∫ B︱▽u︱2dx+1/2ε2∫Bu23dx的径向极小元uε的渐近性态。通过建立径向极小元uε的H1局部收敛性,给出了u2ε3收敛到0的速度估计。
在函數類空間:W={u(x)=[sin f(r)eidθ,cos f(r)]∈H1(B,S2);u|墜B=g}中,研究Landau-Lifshitz型汎函Eε(u,B)=1/2∫ B︱▽u︱2dx+1/2ε2∫Bu23dx的徑嚮極小元uε的漸近性態。通過建立徑嚮極小元uε的H1跼部收斂性,給齣瞭u2ε3收斂到0的速度估計。

In this dissertation,Asymptotic behavior of the radial minimizer uε of the Landau-Lifshitz function Eε(u,B)=12∫B|▽u|2dx+12ε2∫dx,in W={u(x)=[sin f(r)eidθ,cosf(r)]∈H1(B,S2);u|B=g};u|B=g} has been studied.And several estimates of the convergence rate of u 23 to 0 have been proposed by establishing the local convergence of the radial minimizer uε in the H1 sense.
