摘 要: 最近,Bethuel-Riviete研究了稳态Ginzburs-Landau超导模型在给定边界切向电流条件之下,其极小素在小参数ε→0时的渐近行为.得到了它们的子列在中收敛到一个调和映照的结论。其中αi是奇点.d>0是边界上切向电流的拓扑度。本文通过一系列更精细的估计,把这种收敛性推广到和中去.其中a∈(0,1),k为任意正整数。 Bethuel-riviere stydied recently the asymtotic behavior of the Ginzburg-Landau model of superconductivity under the current condition in the tangent direction of the given boundary and its minimum element with parament ε that tends to zero. He deduced the result that their subsequence convergent to a harmonic mapping in H(Ω\where αi is a sigular point and d >0 is the topolosical degree of the tangent i=1current on the boundary. This paper extend the convergence into and through a series of the more accurate estimates,where a∈(0, 1 ) and ki=1is an arbitrary positive constant.
