**Title:** Random polytopes: An introduction and recent developments-Part II

**Speaker: **Julian Grote (PhD Student, University of Bochum and Case Western Reserve University)

**Abstract: **Random polytopes are among the most classical and popular models considered in stochastic geometry, and their study has become a rapidly developing branch of mathematics at the borderline between geometry and probability. …Read more.

**Title: **Convex Geometry and Minkowski’s Linear Forms Theorem in Elementary Function Arithmetic

**Speaker:** Greg Knapp (Case Western Reserve University)

**Advisor:** Colin McLarty (Professor, Case Western Reserve University)

**Abstract: **A classical question in formal logic is “how much mathematics do we need to know in order to prove a given theorem?” Of particular interest is Harvey Friedman’s grand conjecture: that every known mathematical theorem involving only finitary mathematical objects can be proven from Elementary Function Arithmetic (EFA)—a weaker variant of Peano Arithmetic. …Read more.

**Title:** Martingales and a generalization

**Speaker:** Christian Gromoll (Associate Professor, University of Virginia)

**Abstract: **One of the fundamental objects in probability theory is the martingale, which together with its siblings the submartingale and supermartingale can be thought of as a random analogue of the familiar monotone sequence of numbers (constant, nondecreasing, nonincreasing). …Read more.

**Title:** Solution uncertainty quantification for differential equations

**Speaker:** Oksana Chkrebtii (Assistant Professor, The Ohio State University)

**Abstract: When models are defined implicitly by systems of differential equations without a closed form solution, small local errors in finite-dimensional solution approximations can propagate into large deviations from the true underlying state trajectory.** …Read more.
