SUMMARY:Workshop / Seminar:Math Grad Show and Tell Seminar: Magic or Math?
DESCRIPTION:We examine the math behind various magic tricks. As a first example\, a card trick is interpreted through a combinatorial lens and illustrates how structured encoding and permutation strategies allow for complete recovery of missing data. Time permitting\, we will show how to generalize these tricks to decks of arbitrary size.

SUMMARY:Workshop / Seminar:Algebraic Geometry Seminar: Curious properties of Chow rings of matroids
DESCRIPTION:The Chow rings of matroids were constructed by Feichtner—Yuzvinsky as the Chow ring of smooth\, but typically noncompact\, toric varieties. They satisfy remarkable Hodge theoretic properties that are satisfied by a smooth projective variety. These special properties became the start of combinatorial Hodge theory\, and played a key role in the resolution of the Heron-Rota-Welsh conjecture on log-concavity of characteristic polynomials of matroids\, and the Dowling—Wilson top-heavy conjecture. I will survey some properties of Chow rings and K-rings of matroids\, including the construction of an exceptional Hirzebruch—Riemann—Roch theorem. I will touch on some progress on open conjectures surrounding real-rootedness of Poincare polynomials of the Chow rings of matroids\, and their connection to combinatorial commutative algebra.

SUMMARY:Workshop / Seminar:Bike Repair Hours
DESCRIPTION:Does your bike need a tune-up? Need help fixing a flat or getting your gears to shift smoothly? \nSign up for a 30-minute slot and your bike for peer-to-peer bike repair and maintenance. Our volunteers can help you diagnose bike problems\, guide you through repairs\, and provide the tools & materials needed to get you back to riding.\n\nEvery Wednesday from 4-6pm and Friday from 3-5:30pm in the Duderstadt Fabrication Underground (B430-Lower Level) SIGN UP HERE: https://tr.ee/Lp9kLnnfP9\n \nThe Duderstadt Fabrication Underground's Bike Repair rack is available for use during all operation hours (M-F 12-6p). WoW Volunteers will only be there at our dedicated support hours with additional materials (tire patches\, grease\, etc). \n\nThis is NOT a drop-off service: ALL participants are expected to stay and participate in repairs to learn basic bike maintenance with the support of our volunteers. Expect to get your hands dirty and leave feeling more confident in your skills!\n\nIf you are interested in becoming a volunteer at any skill level for our new program\, please email wolverinesonwheels-admin@umich.edu or sign up here: https://docs.google.com/spreadsheets/d/1QVMuOatF-toPc_ky9QIAeeD0ob-ndBGA4uUFm9EAZ0g/edit?usp=sharing

SUMMARY:Workshop / Seminar:RTG Geometry Topology Dynamics Seminar        Representations of quadratic forms via homogeneous dynamics I
DESCRIPTION:Let $q\,Q$ be two integral quadratic forms in $m < n$ variables. One can ask when $q$ can be represented by $Q$ - that is\, whether there exists an $n \times m$-integer matrix $T$ such that $Q \circ T = q$. Naturally\, a necessary condition is that such a representation exists locally\, meaning over the real numbers and modulo $N$ for every positive integer $N$. In the absence of local obstructions\, does a (global) representation of $q$ by $Q$ exist? This question is particularly delicate when the codimension $n-m$ is small\, with codimension $2$ being the most challenging.\n\nIn the first talk\, we will give a broad introduction to Linnik-type equidistribution problems (e.g. for periodic geodesics on the modular surface) in the context of the above question for quadratic forms. We will also explain some ideas of Linnik’s ergodic approach to such problems.\n\nNote a second talk in the Geometry Seminar on Thursday.
