Title: The sign of scalar curvature on Kaehler blowups
Abstract: In Kaehler geometry there is a compelling interaction between the curvature of the metric and the underlying algebro-geometric structure. One example is that positivity of the scalar curvature forces the the Kodaira dimension to be negative. I will explain a recent resolution to the question of whether positive scalar curvature is preserved under birational transformation of Kaehler surfaces, resulting in a classification.
