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: Dependency measures and copulas for multidimensional infinitely divisible distributions
Speaker: Wesley Maddox (Case Western Reserve University)
Advisor: Wojbor Woyczynski (Professor, Case Western Reserve University)
Abstract: Multivariate Linnik distributions, despite their potential usefulness, have not been well-studied due to their difficulty in finding representations and estimators. …Read more.

Title: Bayesian variable selection using Lasso
Speaker: Yuchen Han (Case Western Reserve University)
Advisor: Anirban Mondal (Assistant Professor, Case Western Reserve University)
Abstract: This thesis proposes to combine the stochastic search variable selection (SSVS) approach and Bayesian Lasso approach by introducing a double exponential distribution on the conditional prior of the regression parameters given the indication variables. …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.
