- Description:
- We study plurisubharmonic functions and their applications to K\"ahler geometry. We begin by studying regularity of envelopes of plurisubharmonic functions, particularly when the reference form is degenerate. This is then applied to show regularity of geodesic of K\"ahler metrics on singular varieties, as well as regularity of certain geodesic rays....

- Description:
- This dissertation examines how one pervasive state institution¬—schools—shapes the political behavior of young people along the lines of race and ethnicity. I make four primary claims. First, I show that the content of traditional civic education courses privileges the political experiences of white political actors. Second, I argue that this...

- This dissertation investigates a number of models and algorithms in the context of optimization under uncertainty. The focus is on risk-averse optimization, where risk aversion is modeled via stochastic dominance, utility theory, and distributionally robust optimization. We first investigate an investment model with fixed contribution rates, optimize asset-allocation decisions in...
