Discrete Analysis

Given $1le pinfty$ and $k$ what is the minimal $n$ such that $ll_p^n$ almost isometrically contain all $k$-dimensional subspaces of $L_p$? I’ll survey what is known about this problem and then concentrate on a recent result, basically solving the problem for even $p$. The proof uses a recent result of Batson, Spielman and Srivastava.
