    Speaker: Tatyana Sharpee (Salk Institute for Biological Studies) Title: Hyperbolic geometry of the olfactory space Abstract: The sense of smell can be used to avoid poisons or estimate a food’s nutrition content because biochemical reactions […]

  • Deregulation through Direct Democracy: Lessons from Liquor

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker:  Sarah Moshary (University of Chicago) Title:  Deregulation through Direct Democracy: Lessons from Liquor Abstract:  This paper examines the merits of state control versus private provision of spirits retail, using the 2012 deregulation of […]

  • Inequality Aversion, Populism, and the Backlash Against Globalization

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Pietro Veronesi (University of Chicago) Title: Inequality Aversion, Populism, and the Backlash Against Globalization Abstract: Motivated by the recent rise of populism in western democracies, we develop a model in which a populist […]

  • Machine Learning Physics: From Quantum Mechanics to Holographic Geometry

    Speaker: Yi-Zhuang You (UCSD) Title: Machine Learning Physics: From Quantum Mechanics to Holographic Geometry Abstract: Inspired by the "third wave" of artificial intelligence (AI), machine learning has found rapid applications in various topics of physics research. Perhaps one of the most […]

  • Credible Mechanisms

    Speaker: Shengwu Li (Harvard) Title: Credible Mechanisms Abstract: Consider an extensive-form mechanism, run by an auctioneer who communicates sequentially and privately with agents. Suppose the auctioneer can deviate from the rules provided that no single agent […]

  • A taste of noncommutative convex algebraic geometry

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Bill Helton (UC San Diego) Title:  A taste of noncommutative convex algebraic geometry Abstract: The last decade has seen the development of a substantial noncommutative (in a free algebra) real and complex algebraic […]

  • Double affine Hecke algebras

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Pavel Etingof (MIT) Title:  Double affine Hecke algebras Abstract: Double affine Hecke algebras (DAHAs) were introduced by I. Cherednik in the early 1990s to prove Macdonald's conjectures. A DAHA is the quotient of the […]
