摘要: 该文研究了具有迅速振荡Neumann边值齐次化问题解的W1,p收敛率.此类问题在齐次化的高阶逼近理论中有着很重要的作用,其往往被用来描述边界分层想象.该文主要用到了解的积分表示、振荡积分估计以及周期函数Fourier展开等核心思想和技术.

关键词: 齐次化, 收敛率, 振荡, Neumann函数

Abstract: In this paper, we shall strengthen our results on the W1,p convergence rates for homogenization problems for solutions of partial differential equations with rapidly oscillating Neumann boundary data. Such a problem raised due to its importance for higher order approximation in homogenization theory, which gives rise to the so-called boundary layer phenomenon. Our techniques are based on integral representation of the solutions as well as analysis of oscillatory integrals, in conjunction with Fourier expansion of the oscillating periodic function.

Key words: Homogenization, Convergence rates, Oscillating, Neumann functions
