  • The virtual fundamental class in symplectic geometry

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Dusa McDuff (Columbia University)  Title: The virtual fundamental class in symplectic geometry Abstract: Essential to many constructions and applications of symplectic geometry is the ability to count J-holomorphic curves. The moduli spaces […]

  • Computational Principles of Auditory Cortex

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Xiaoqin Wang (Johns Hopkins University) Title: Computational Principles of Auditory Cortex Abstract: Auditory cortex is located at the top of a hierarchical processing pathway in the brain that encodes acoustic information. This brain region is crucial […]

  • Recent progress on mean curvature flow

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Robert Haslhofer (University of Toronto) Title: Recent progress on mean curvature flow Abstract: A family of surfaces moves by mean curvature flow if the velocity at each point is given by the mean curvature […]

  • Innovation in Cell Phones in the US and China: Who Improves Technology Faster?

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Richard B. Freeman (Harvard University and NBER) Title: Innovation in Cell Phones in the US and China: Who Improves Technology Faster? Abstract: Cell phones are the archetypical modern consumer innovation, spreading around […]

  • Inference for the Mean

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Ulrich Mueller (Princeton) Title: Inference for the Mean Abstract: Consider inference about the mean of a population with finite variance, based on an i.i.d. sample. The usual t-statistic yields correct inference in large samples, […]

  • Optimally Imprecise Memory and Biased Forecasts

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Michael Woodford (Columbia) Title: Optimally Imprecise Memory and Biased Forecasts Abstract: We propose a model of optimal decision making subject to a memory constraint. The constraint is a limit on the complexity of memory […]

  • Sentiment and Speculation in a Market with Heterogeneous Beliefs

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Ian Martin (LSE) Title: Sentiment and Speculation in a Market with Heterogeneous Beliefs Abstract: We present a dynamic model featuring risk-averse investors with heterogeneous beliefs. Individual investors have stable beliefs and risk aversion, but […]

  • On the geometry and topology of initial data sets in General Relativity

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Greg Galloway (University of Miami) Title: On the geometry and topology of initial data sets in General Relativity Abstract: A theme of long standing interest (to the speaker!) concerns the relationship […]

  • Quality Externalities on Platforms: The Case of Airbnb

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker:  Sonia Jaffe  (Microsoft) Title: Quality Externalities on Platforms: The Case of Airbnb Abstract:  We explore quality externalities on platforms: when buyers have limited information, a seller's quality affects whether her buyers return […]

  • Hyperbolic geometry of the olfactory space

    CMSA 20 Garden Street, Cambridge, MA, United States

    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 […]
