A characterization of idempotent Schur multipliers

Csongor Beke, Marcel K. Goh, Hamed Hatami +2

We prove that every idempotent Schur multiplier is a finite signed sum of contractive idempotent Schur multipliers. This was conjectured by Katavolos and Paulsen in 2003 and previo…

$Δ + 300$ is a Bound on the Adjacent Vertex Distinguishing Edge Chromatic Number

Hamed Hatami

An adjacent vertex distinguishing edge-coloring or an \avd-coloring of a simple graph $G$ is a proper edge-coloring of $G$ such that no pair of adjacent vertices meets the same set…
