Thursday, 03 November 2016, 14:00 at Cambridge University Engineering Department, JDB Seminar Room – The matrix logarithm, when applied to symmetric positive definite matrices satisfies a notable concavity property in the positive semidefinite (Loewner) order. This concavity property is a cornerstone result in the study of operator convex functions and has important applications in matrix concentration inequalities and quantum information theory. In this talk …
