Fitting a Sobolev function to data

Charles L. Fefferman, Arie Israel, Garving K. Luli

We exhibit an algorithm to solve the following extension problem: Given a finite set $E \subset R^{n}$ and a function $f : E \to R$ , compute an extension $F$ …

An arithmetic-geometric mean inequality for products of three matrices

Arie Israel, Felix Krahmer, Rachel Ward

Consider the following noncommutative arithmetic-geometric mean inequality: given positive-semidefinite matrices $A_{1}, \dots, A_{n}$ , the following holds for each i…

Sobolev Extension By Linear Operators

Charles L. Fefferman, Arie Israel, Garving K. Luli

Let $L^{m, p} (R^{n})$ be the Sobolev space of functions with $m^{t h}$ derivatives lying in $L^{p} (R^{n})$ . Assume that $n < p < \infty$ . For $E \subset R^{n}$ , let $L^{m, p} (E)$ denote the…
