Finding at Least One Point in Each Connected Component of a Real Algebraic Set Defined by a Single Equation
Deciding efficiently the emptiness of a real algebraic set defined by a single equation is a fundamental problem of computational real algebraic geometry. We propose an algorithm ...

Connecting the top-down to the bottom-up: Pricing CDO under a Conditional Survival (CS) model
In this paper, we use exact simulation to price CDO under a new dynamic model, the Conditional Survival (CS) model, which provided excellent calibration to both iTraxx tranches an...
