Nearly orthogonal vectors

How can d+k vectors in R^d be arranged so that they are as close to orthogonal as possible? We show intimate connection of this problem to the problem of equiangular lines, and to the problem of bounding the first moment of isotropic measures. Using these connections, we pin down the answer precisely for several values of k and establish asymptotics for all k. Joint work with Chris Cox.

Effective Reifenberg theorems for measures

The Jones' $β$-numbers quantify how ``linear'' is the support of a measure. These have important uses in singularity analysis of solutions to PDE and harmonic analysis. In this talk, I explain joint work with Aaron Naber and Daniele Valtorta which gives quantitative control and Lipschitz structure on measures satisfying natural conditions on the $β$-numbers, and generalizations of our results to infinite-dimensional spaces. Our work can be viewed as an ``analyst's traveling-salesman'' type theorem.
