SUMMARY:Workshop / Seminar:Learning seminar in algebraic combinatorics: How to describe general torsion classes?
DESCRIPTION:Last time we saw that we can describe torsion classes of quiver representations of Type A_n by bracket vectors. In this talk\, I will give some more general approaches to describing torsion classes\, First I will illustrate them through the familiar Type A_n example. I will also demonstrate how to use them to describe the torsion classes of the representations of the Kronecker quiver. In the second part of the talk\, I will use these new descriptions to construct a dual notion of torsion classes\, the torsion free classes\, and prove that torsion classes form a complete lattice.

SUMMARY:Workshop / Seminar:Student Number Theory: An introduction to Borcherds lifts
DESCRIPTION:Let L be an even lattice of signature (2\, n). The Borcherds lifting takes a weakly holomorphic modular form f for Mp(2\, ℤ) of weight 1-n/2 valued in ℂ[L'/L] and produces a meromorphic modular form Ψ(f) for O⁺(L). The divisors of Borcherds lifts are supported on Heegner divisors. In fact\, the weight and the divisor of Ψ(f) are completely determined by the constant term and the principal part of the Fourier expansion of f respectively. Furthermore\, Borcherds lifts admit infinite product expansions known as Borcherds products. In this talk\, we will use the regularized theta lifts of weak Maass forms to sketch the construction of Borcherds lifts.

SUMMARY:Workshop / Seminar:Department Colloquium | The Final Fermilab muon g-2 result
DESCRIPTION:The muon magnetic moment anomaly arises due to quantum interactions of muons and the vacuum\, mostly due to quantum electrodynamics (QED)\, but with contributions from ALL Standard Model interactions as well as Beyond-Standard-Model physics. The Fermilab muon g-2 experiment employed a 50m circumference 1.45 T magnetic storage ring and measured the precession of muons with respect to the momentum of the cyclotron orbits for six years. The precision of the final Fermilab result\, 127 ppb\, combines statistically limited measurement of the muon precession and measurement of the magnetic field averaged over the muon storage volume employing novel magnetometry and analysis techniques developed at UM. The Standard Model calculation\, based on known physics\,  is confounded by the strong interaction and has incorporated new approaches based on Lattice Gauge Theory. Experiment and theory are currently consistent\, though the theory uncertainty has gotten worse while the experimental uncertainty has improved. In this talk I will tell the story of this precision measurement.

SUMMARY:Lecture / Discussion:MIPSE Seminar | Extreme Matters\, Pressure to Explore New Worlds\, Exotic Solids\, and Star Power
DESCRIPTION:Abstract: \nA science revolution is underway with the discovery of thousands of planets outside of our solar system\, the creation of revolutionary materials\, and the potential for harnessing fusion energy. Unlocking these discoveries hinges on our ability to understand and manipulate matter to and beyond atomic pressures\, conditions that alter the nature of atoms themselves. At such conditions our intuition for matter begins to breakdown\, with hydrogen becoming a metal and perhaps a superconducting super-fluid\, water becoming superionic where protons flow through a compact oxygen crystal\, and unbound electrons getting squeezed interior to core orbitals of an atom. I will show how laboratory laser experiments are opening this science frontier at light speed\, revealing how we might make transparent aluminum-like in Star Trek\, a new exploration into the nature and implications of planets-potential platforms for life throughout the universe\, and controlled thermonuclear fusion. You might take a look at one of our videos as a primer to our discussion: https://www.youtube.com/watch?v=NqabT21d8VM\n\nAbout the Speaker: \nGilbert ‘Rip’ Collins is Tracy Hyde Harris Professor of Mechanical Engineering and Physics and Astronomy\, and Associate Director for the Laboratory for Laser Energetics at the University of Rochester. He received his Ph.D. in Physics from Ohio State University. From 1989 to 2016\, he held positions at Lawrence Livermore National Laboratory\, including Group Leader\, Physics Associate Division Leader\, Director for the Center for High Energy Density Physics\, and Distinguished Member of the Technical Staff. Rip works with a world-class team of scientists exploring the nature and implications of matter at conditions where external forces overwhelm the quantum forces of the atom and the microphysics leading to thermonuclear fusion. He is the Director of the NSF Physics Frontier Center for Matter at Atomic Pressures. He holds visiting Professorships at Oxford University and the University of Edinburgh. He is a recipient of the Bridgman Award\, APS Fellow\, AAAS Fellow\, APS Award for Excellence in Plasma Physics\, DOE Weapons Recognition of Excellence Award\, NNSA Award for Excellence for Stockpile Stewardship Program\, and NNSA Science and Technology Award.\n\nThis seminar is free and open to the public. It will be conducted in person and on Zoom\, please check MIPSE website for details: https://mipse.umich.edu/seminars_2526.php

SUMMARY:Workshop / Seminar:Algebraic Geometry Seminar: Intersections in the Bézout Range
DESCRIPTION:Given subvarieties X\, Y of a complex algebraic variety S of complementary dimension\, must they intersect?\n\nFor projective space this follows from the classical Bézout theorem\, and an analogue for simple abelian varieties was established by Barth. The moving lemma further suggests that\, after suitable translations\, one may even ensure intersections of the expected dimension.\n\nI will present new refinements in the abelian setting and discuss extensions to Shimura varieties\, framed within the ''completed Zilber–Pink philosophy.''

SUMMARY:Lecture / Discussion:\"Reform as Process: Implementing Change in Public Bureaucracies\" Book Launch
DESCRIPTION:Join us for the launch of Martin J. Williams’s Reform as Process\, an in-depth study of civil service reform across six African countries. Williams will be joined by discussants Donald Moynihan (Ford School) and Omolade Adunbi (Anthropology and African and African American Studies). Elizabeth Popp Berman (Organizational Studies) will moderate.\n\n\nMore about the book:\nBuilding an effective civil service is crucial for public service delivery and good governance\, but reforming bureaucratic institutions is notoriously difficult. This book takes a fresh perspective on this challenge by documenting and analyzing the implementation of more than one hundred reforms initiated by six African countries over the last thirty years.\n\nMartin J. Williams shows that these efforts largely fell short of their goals because they typically approached organizational change as a matter of changing formal structures and processes through one-off projects. Some did yield positive changes\, however\, when they were able to create opportunities for civil servants to discuss performance and how to improve it. Drawing on this evidence\, Williams develops a new theory of how systemic reforms can lead to meaningful change—not by trying to force it through top-down interventions but by catalyzing an ongoing and decentralized process of continuous improvement.\n\nReform as Process makes theoretical and empirical contributions to research on organizational performance\, civil service reform\, and public service delivery\, and it shares practical insights and strategies to help reformers around the world achieve meaningful change in their organizations.\n\nAbout the Author:\nMartin J. Williams is associate professor of organizational studies and (by courtesy) political science and public policy at the University of Michigan\, as well as associate faculty at the Blavatnik School of Government\, University of Oxford.
