    Cutting and Stacking Constructions in Infinite Ergodic Theory Prof. Kelly Yancey University of Maryland Operator Algebras and Dynamics Seminar

    View Abstract

    In ergodic theory two properties that are very different, though not exclusive, are rigidity and weak mixing. Recall that there are many examples of homeomorphisms of the two-torus that display both of these properties. A natural question to ask is what happens if we consider systems that preserve an infinite measure, like Lebesgue measure on the positive reals. This is part of the set-up in infinite ergodic theory. During this talk we will discuss rigidity verses various types of weak mixing in infinite ergodic theory. We will also construct examples of transformations that have these desired properties. Our examples will be via the method of cutting and stacking. This is joint work with Rachel Bayless.

    Dynamic programming and the jungle Sommer Gentry USNA Basic Notions Spring 2014

    View Abstract

    Stochastic, dynamic optimization problems are incredibly varied and difficult to solve. It's no surprise that different research communities have developed different algorithms, notation, and names for algorithms tuned to different aspects of the "curse of dimensionality". Solution methods go under the names of reinforcement learning, markov decision processes, stochastic programming, approximate dynamic programming, and more. I'll offer a road map through the jungle, starting with the celebrated Bellman (Hamilton-Jacobi) equation that recursively defines the best decision to make at any time point t as a function of the expected value of making optimal decisions from time t+1 forward.
