Topic:

Yuzvinsky's conjecture, posed in 1981, is concerned with a certain

matrix coloring problem which arose from the classical studies of sums

of squares. In this talk I will present a proof of the conjecture in

the case of square matrices. The ideas of the proof are inspired by

algebra and topology, despite the purely combinatorial nature of the

conjecture itself.
