    On low temperature kinetic theory; spin diffusion, anyons, Bose Einstein condensates
    published on November 18, 2014

    On low temperature kinetic theory; spin diffusion, anyons, Bose Einstein condensates

    By Leif Arkeryd

    CIRM

    To illustrate specifically quantum behaviours, the talk will consider three typical problems for non-linear kinetic models evolving through pair collisions at temperatures not far from absolute zero. Based on those examples, a number of differences between quantum and classical Boltzmann theory ...

    Introduction on inverse problems : General introduction (part 1/2)

    By Michel Cristofol

    CIMPA

    The goal of this course is to give a short survey on the domain of Inverse Problems. After a general introduction I will focus on the parabolic operators and I will present around the same toy problem different technics: - the Dirichlet to Neumann methodology (see [1]), - the Carleman ...

    PDEs on the Homogeneous Space of Positions and Orientations

    By Remco Duits

    IHP

    ... 2]. this is done by a Fourier transform on $\mathbb M$, cf. [2]. We solve the following PDEs on $\mathbb M$ numerically: – Nonlinear Diffusions on $\mathbb M$, cf. [3], – Mean Curvature Flows and Total Variation Flows on $\mathbb M$, cf. [4] ($d= 2,3$), [5, 6] ($d= 2$), – Eikonal ...

    The seventh Starling: the Wonders of Collective Animal Behaviour

    By Andrea Cavagna

    IHP

    The wonderful evolutions of the great flocks of birds across the skies of our cities, often in aerial duel with a falcon, are both a fascinating sight, and a scientific mystery. How does the flock keep its staggering cohesion? How can it take decisions, as changing direction, or landing on a tree, ...

    Modèles mathématiques des épidémies

    By Etienne Pardoux

    CIRM

    Il y a cent ans, Sir Ronald Ross tentait de convaincre ses collègues médecins que l'épidémiologie doit être étudiée avec l'aide des mathématiques. Le but de cet exposé est d'expliquer pourquoi les mathématiques sont essentielles pour combattre les épidémies, et de donner quelques ...

    The local Gan-Gross-Prasad conjecture for unitary groups

    By Raphaël Beuzart Plessis

    CIRM

    The local Gan-Gross-Prasad conjectures concern certain branching or restriction problems between representations of real or p-adic Lie groups. In its simplest form it predicts certain multiplicity-one results for "extended" L-packets. In a recent series of papers, Waldspurger has settled the ...

    Transfer Learning and Collaborative AI

    By Gilles Wainrib

    IHES

    ... What if we could share and connect those algorithms and create the conditions for a cross-fertilization between these powerful artificial intelligence systems ? In this talk, we will discuss the fundamental role of transfer learning to foster the emergence of collaborative artificial intelligence ...

    Subsurface flow with uncertainty : applications and numerical analysis issues

    By Julia Charrier

    CIRM

    ... We deal with the uncertainty thanks to a Monte Carlo method and use a stochastic particle method to approximate the solution of the transport-diffusion equation. Error estimates will be established and numerical results (obtained by A.Beaudoin et al. using PARADIS Software) will be presented. In ...

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 +.
