The Gaussian Correlation Inequality for Symmetric Convex SetsDec 03 2010Mar 02 2013The paper is to prove the Gaussian correlation conjecture stating that, under the standard Gaussian measure, the measure of the intersection of any two symmetric convex sets is greater than or equal to the product of their measures. Characterization of ... More
