    Control of the motion of a set of particles

    By Olivier Glass

    CIRM

    We consider the problem of lagrangian controllability for two models of fluids. The lagrangian controllability consists in the possibility of prescribing the motion of a set of particle from one place to another in a given time. The two models under view are the Euler equation for incompressible ...

    Class number statistics for imaginary quadratic fields

    By Pär Kurlberg

    CIRM

    The number $F(h)$ of imaginary quadratic fields with class number $h$ is of classical interest: Gauss’ class number problem asks for a determination of those fields counted by $F(h)$. The unconditional computation of $F(h)$ for $h \le 100$ was completed by M. Watkins, and K. Soundararajan has ...

    Affine Volterra processes and models for rough volatility
    published on November 21, 2017

    Affine Volterra processes and models for rough volatility

    By Martin Larsson

    CIRM

    ... Classical affine diffusions constitute a special case, but affine Volterra processes are neither semi-martingales, nor Markov processes in general. Nonetheless, their Fourier-Laplace functionals admit exponential-affine representations in terms of solutions of associated deterministic integral ...

    Class forcing and topos theory

    By David Michael Roberts

    IHES

    ... There is a more general notion of forcing invented by Easton to create new subsets of arbitrarily large sets, namely class forcing, where one starts with a partially ordered class. The existing theory of class forcing is entirely classical, with no corresponding intuitionist theory as in ordinary ...

The search tool allows you to search through the video titles, abstracts, and other metadata. Various filters are proposed to refine the results. The results can be sorted by date or by relevance (default).

The search tool recognizes the following operators:
  • Quotes ("sample") returning results containing the exact expression;
  • Plus sign (sample+of+search) returning results containing all of the terms separated by +.
