Title:  Sumner Myers Prize lecture: The geometry of (some) noncommutative surfaces

Abstract:  The correspondence between commutative graded rings and projective algebraic varieties is well-known. Perhaps surprisingly, geometric techniques have also been highly successful in understanding noncommutative graded rings, particularly those of low dimension: the analogues of projective curves and projective surfaces. Noncommutative curves are understood, and noncommutative surfaces are an active research area. We present our recent classification of birationally commutative projective surfaces, and discuss open problems.
