SUMMARY:Workshop / Seminar:A Dynamic Evaluation of Parental Marriage and Children’s Skill Development
DESCRIPTION:Children who grow up in two-parent households score 0.2-0.4 standard deviations higher on covariate-adjusted cognitive skill measures than children in single-parent households. This paper analyzes the extent to which these differences reflect causal effects of marriage versus selection. We develop a dynamic Roy model that allows for selection into and out of marriage\, with cognitive skill evolving according to a dynamic latent factor model. A long panel of marriage decisions permits identification of unobserved heterogeneity jointly affecting both marriage and skill development. Model estimates indicate that marriage improves skill development. A decomposition analysis suggests that differences in the technology of skill formation between the married and single states explains 30% of the skill difference between children growing up in two-parent and one-parent households while income differences explain 16%.

SUMMARY:Workshop / Seminar:Learning seminar in algebraic combinatorics: C(-)ambrian Lattice II : c-sortable elements and c-clusters
DESCRIPTION:Building on the type A example from last week\, we will explore Cambrian lattices for general Coxeter groups. For a Coxeter element c\, we will introduce c-sorting words and c-sortable elements. We will see how these can be used to describe interesting lattice congruences and connect the quotient lattices to generalized associahedra via c-clusters and c-noncrossing elements.

SUMMARY:Workshop / Seminar:Student Number Theory: Etale Cohomology is Galois Cohomology
DESCRIPTION:In this talk\, we will discuss the definition of the etale site and show that the definition of H_et^i is the same as Galois cohomology. As a corollary\, we easily derive a proof of Hilbert's Theorem 90.

SUMMARY:Ceremony / Service:Career Celebration: Barbara Anderson
DESCRIPTION:Join us for a celebration of Dr. Barbara Anderson's career from 3-5pm on Wednesday\, April 1\, 2026. Remarks will begin at 3:30 pm.\n\nBarbara Anderson is Ronald A. Freedman Collegiate Professor of Sociology and Population Studies and a scholar of social\, economic\, and demographic change.  She has worked in these areas on the Russian Empire\, Soviet Union and former Soviet Union\, China\, and South Africa\, which provides data insights about common problems in sub-Saharan Africa. Dr. Anderson has studied infant and child survival\, causes and patterns of adult mortality\, trends in orphanhood\, perceptions of environmental problems and actions taken to address these problems\, changes in material standard of living and characteristics of the growing African middle class.\n\nWe will be in person in 1040 LSA on the University of Michigan campus but can also accommodate virtual visitors via Zoom if you can't be there in person.\n\nPlease RSVP for the Barbara Anderson celebration no later than March 20th for catering purposes: https://docs.google.com/forms/d/e/1FAIpQLScmEEig5acumKln055lxLKPKqi8dtXN7-0g7OnLftjKluBANQ/viewform

SUMMARY:Workshop / Seminar:Department Colloquium |  The Bootstrap Program for the Strong Force
DESCRIPTION:In the 1960s\,  the dominant approach to the strong interaction was the S-matrix bootstrap: the idea that the hadronic spectrum and scattering amplitudes could be determined from the general principles of causality and unitarity. This program culminated in the Veneziano amplitude which gave birth to string theory\, but was abandoned as an approach to the strong force after the identification of Quantum Chromodynamics (QCD) as the microscopic theory of hadron physics. Yet QCD at low energies remains largely unsolved. I will describe how modern bootstrap methods\, powered new theoretical insights and computational techniques\, allow us to revisit this classic program with unprecedented rigor.  Consistency of pion scattering — with minimal assumptions about the lightest resonances — leads to the emergence of Regge trajectories from the bootstrap bounds. The bootstrap approach becomes particularly sharp in the limit of a large number of colors. The low-lying spectrum of the extremal solutions shows a tantalizing\, and still somewhat mysterious\, quantitative proximity to the real-world meson masses. I will discuss what we are learning from these results and outline open questions on the path toward a bootstrap solution of large N QCD.

SUMMARY:Workshop / Seminar:Exotic R4
DESCRIPTION:Isomorphisms between objects that hold in the topological category but not in the smooth category\, more concisely referred to as exotic phenomena\, are central objects of study in topology and have guided the field's development for more than half a century. In this talk\, we give an overview of some basic tools used in the study of 4-manifolds and use them to give an outline of the construction of exotic R4\, a smooth manifold which is homeomorphic to the standard R4 but not diffeomorphic.
