The Sylvester--Gallai dimension of graphs

Zeev Dvir

For an undirected graph , its \emph{Sylvester--Gallai dimension} is the largest affine dimension of a configuration of distinct real points indexed by i…

Rank of incidence matrices over integers modulo a prime power

Zeev Dvir

In this note we prove an upper bound on the -rank of the incidence matrix of points and hyperplanes in , improving a recent bound of Laba…

Rank-metric separation in irreducible representations of finite groups

Zeev Dvir

We give a general lower bound on the rank of matrices of the form with an irreducible representation of a finite group . The main…

Tensor rank and dimension expanders

Zeev Dvir

We prove a lower bound on the rank of tensors constructed from families of linear maps that `expand' the dimension of every subspace. Such families, called {\em dimension expanders…

Linear Hashing with guarantees and two-sided Kakeya bounds

Manik Dhar, Zeev Dvir

We show that a randomly chosen linear map over a finite field gives a good hash function in the sense. More concretely, consider a set and…

Proof of the Kakeya set conjecture over rings of integers modulo square-free

Manik Dhar, Zeev Dvir

A Kakeya set is a set containing a line in each direction. We show that, when is any square-free integer, the size of the smallest Kakeya…
