  • CMSA Special Seminar: Deformations to the Complex Plane, Novel Asymptotic Techniques, and the Large t- Asymptotics of the Riemann Zeta Function

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    CMSA Special Seminar Speaker: Thanasis Fokas, University of Cambridge Title: Deformations to the Complex Plane, Novel Asymptotic Techniques, and the Large t- Asymptotics of the Riemann Zeta Function Abstract: The Unified Transform (also known as the Fokas method) is a powerful new method for solving boundary value problems for linear and for integrable nonlinear PDEs. For […]

  • Mathematical Economics Seminar: Algorithmic Decision-Making

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Mathematical Economics Seminar: Algorithmic Decision-Making Speaker: Ashesh Rambachan, MIT Title:  Human Decisions and Machine Predictions in Multistage Systems Abstract: Many high-stakes decisions go through successive stages of human review before a final decision is made, complicating efforts to evaluate both the human decision-makers and algorithmic counterfactuals. We develop a framework for evaluating both humans and algorithms […]

  • Geometry and Quantum Theory Seminar

    Science Center 507 1 Oxford Street, Cambridge

    Joint Math/CMSA Geometry and Quantum Theory Seminar Speaker: Dan Freed, Harvard Title: Path integral quantization of particles via probability (Part 2) Abstract: I will pick up where I left off last week.  The first half of the lecture will cover the general strategy of constructing a quantum system using Markov processes, as described in Section […]

  • Finite locally free group schemes

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    AI for the Working Mathematician Speaker: Akhil Mathew, University of Chicago Title: Finite locally free group schemes Abstract: The notion of a finite locally free group scheme is a natural generalization of the usual notion of a finite group. Lagrange's theorem states that all nth powers vanish in a group of order n. However, this need […]

  • Life on a Noisy Seascape: Extinction, Growth, and Diversity

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Colloquium Speaker: Mehran Kardar, MIT Title: Life on a Noisy Seascape: Extinction, Growth, and Diversity Abstract: Populations and communities rarely evolve in static environments; their fitness landscapes fluctuate across space and time, forming what may be called a noisy seascape. This talk examines how such variability modifies classical models of population dynamics and community stability. Beginning from the […]
