本文研究无穷维序列空间在一致框架下的非线性manifold n-宽度δn(w,x)，并得到其精确渐进估计，即当1≤p,q≤∞时，Bp,r表示lp,r中的单位球。 In this paper, we study the nonlinear n-width δn(w,x) of infinite dimensional sequence spaces under consistent framework and obtain its accurate asymptotic estimates. That is when 1≤p,q≤∞. Bp,r is the unit sphere in the representation lp,r.
