A generalization of Croot-Lev-Pach's Lemma and a new upper bound for the size of difference sets in polynomial rings

, 2018
Croot, Lev and Pach used a new polynomial technique to give a new exponential upper bound for the size of three-term progression-free subsets in the groups $(\mathbb Z _4)^n$.

A generalization of the Graham-Pollak tree theorem to even-order Steiner distance

Special Matrices
Graham and Pollak showed in 1971 that the determinant of a tree’s distance matrix depends only on its number of vertices, and, in particular, it is always nonzero.
