### Tight embedding of subspaces of $L_p$ in $\ell_p^n$ for even $p$

Seminar Room 1, Newton Institute

#### Abstract

Given $1\le p\infty$ and $k$ what is the minimal $n$ such that $\ell_p^n$ 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.#### Video
