PADS Seminar: The Persistence Landscapes of Affine Fractals

Speaker: Lee Przybylski (ISU) Abstract: We develop a method for calculating the persistence landscapes of affine fractals using the parameters of the corresponding transformations.  Given an iterated function system of affine transformations that satisfies a certain compatibility condition, we prove that there exists an affine transformation acting on the space of persistence landscapes which intertwines … Continue reading PADS Seminar: The Persistence Landscapes of Affine Fractals

Math Logic Seminar: Stationary reflection and singular cardinals

Speaker: by Dima Sinapova (University of Illinois at Chicago) Abstract: Two classical results of Magidor are: from large cardinals it is consistent to have reflection at ℵω+1\aleph_{\omega+1}ℵω+1​, and from large cardinals it is consistent to have the failure of the singular cardinal hypothesis (SCH) at ℵω\aleph_\omegaℵω​. These principles are at odds with each other. The … Continue reading Math Logic Seminar: Stationary reflection and singular cardinals

Discrete Math Seminar: Sufficient Conditions for Perfect Mixed Tilings

Speaker: Eoin Hurley (Universität Heidelberg) Abstract: We develop a method to study sufficient conditions for perfect mixed tilings. Our framework allows the embedding of bounded degree graphs HHH with components of sublinear order. As a corollary, we recover and extend the work of Kühn and Osthus regarding sufficient minimum degree conditions for perfect FFF-tilings (for … Continue reading Discrete Math Seminar: Sufficient Conditions for Perfect Mixed Tilings

Algebra and Geometry Seminar: Tautological classes of matroids

Speaker: Chris Eur (Harvard) Abstract: Algebraic geometry has furnished fruitful tools for studying matroids, which are combinatorial abstractions of hyperplane arrangements. We first survey some recent developments, pointing out how these developments remained partially disjoint. We then introduce certain vector bundles (K-classes) on permutohedral varieties, which we call “tautological bundles (classes)” of matroids, as a … Continue reading Algebra and Geometry Seminar: Tautological classes of matroids
