DESCRIPTION:Abstract: Recent breakthroughs in graph streaming have led to t
he design of single-pass semi-streaming algorithms for various graph color
ing problems such as (Δ+1)-coloring\, degeneracy-coloring\, coloring tria
ngle-free graphs\, and others. These algorithms are all randomized in cruc
ial ways and whether or not there is any deterministic analogue of them ha
s remained an important open question in this line of work.\n\nIn this tal
k\, we will discuss our recent result that fully resolves this question: t
here is no deterministic single-pass semi-streaming algorithm that given a
graph G with maximum degree Δ\, can output a proper coloring of G using
any number of colors which is sub-exponential in Δ. The proof is based on
analyzing the multi-party communication complexity of a related communica
tion game using elementary random graph theory arguments. \n\nBased on joi
nt work with Andrew Chen (Cornell) and Glenn Sun (UCLA).
