Linear Analysis Seminar
Time: 3:00PM - 4:00PM
Location: BLOC 220
Speaker: Larry Brown, Purdue University
Title: Operator monotone functions, operator convex functions, and strongly operator convex functions
Abstract: The three terms denote classes of real-valued functions on intervals, each of which can be defined by matrix inequalities. All or almost all of the talk will be suitable for a general audience, including graduate students, and the talk will include an explanation of what is meant by a matrix inequality. Operator monotone functions are defined by the inequality, f(h1)≤f(h2), whenever h1 and h2 are self-adjoint matrices whose eigenvalues are in the domain of f and h1≤h2 (the meaning of f(h) will also be explained); and the definitions of the other two classes are also very natural. Each of the three classes has other characterizations of four different types, a global condition on f, an integral representation of f, a differential criterion, and a characterization in terms of operator algebraic semicontinuity theory. The main thrust of the talk will be to explain the various characterizations in a parallel way.
