SUMMARY:Applied Math Seminar: Sarah Robinson  (Claremont McKenna College)
DESCRIPTION:Title: Do Taxes Affect Pre-Tax Income Inequality? Evidence from 100 Years of U.S. States \nAbstract: We study how U.S. state taxes have affected pre-tax income inequality during the last century. Our primary analysis focuses on the top marginal personal income and corporate income tax\, and their effect on top incomes and top income shares within each state. The long panel nature of our data\, from 1917 to 2018\, allows us to study the effect of tax adoptions\, tax cancellations\, and tax changes\, and furthermore to assess both immediate and long-term relationships. With event study and synthetic control designs\, we generally find no statistically significant relationship between tax measures and inequality. Some of our point estimates\, as well as a simple two-way fixed effects analysis\, suggest that higher income taxes may reduce top incomes and income shares.

SUMMARY:Claremont Topology Seminar: Iris Yoon (Wesleyan University)
DESCRIPTION:We especially welcome all undergraduates and graduate students to attend topology seminar! \nSpeaker: Iris Yoon (Wesleyan University) \nTitle: Dowker duality\, profunctors\, and spectral sequences \nAbstract: I will present three short\, new proofs of Dowker duality using various poset fiber lemmas. I will introduce modifications of joins and products of simplicial complexes called relational join and relational product complexes. These relational complexes can be constructed whenever there is a relation between simplicial complexes\, which includes the context of Dowker duality and covers of simplicial complexes. In this more general setting\, I will show that the homologies of the simplicial complexes and the relational complexes fit together in a long exact sequence. If time permits\, I’ll discuss similar results for profunctors\, which are generalizations of relations to categories.

SUMMARY:CCMS Colloquium: (Iris Yoon\, Wesleyan University)
DESCRIPTION:Speaker: Iris Yoon\, Professor of Mathematics\, Wesleyan University \nTitle: How Topology Reveals Structure in Neuroscience Data \nAbstract: We live in an exciting time where new data is generated at an exponential rate. Such data explosion necessitates the development of novel methods for studying large\, noisy\, and complex data. One interesting aspect of data is its shape and structure. In this talk\, I will discuss recent developments in applied topology that studies the structure of data. In particular\, I will show how constructions in topology\, such as homology and Dowker complexes\, reveal interesting structures in data. I will discuss the mathematical challenges of extending these constructions to data science\, specifically in neuroscience. \nBio: Iris Yoon is an assistant professor of mathematics at Wesleyan University. She develops novel applications of algebraic topology to data science. \n
