Title: Gubeladze's geometric proof of Anderson's conjecture.
Abstract: Let M be a finitely generated seminormal submonoid of the free
monoid \mathbb Z_+^n and let k be a field. Then Anderson conjectured that
all finitely generated projective modules over the monoid algebra k[M] is
free. He proved this in case n=2. Gubeladze proved this for all n using
the geometry of polytopes. In a series of 3 lectures, we will outline a
proof of this theorem.
