  • A Variational Model for Joint Motion Estimation and Image Reconstruction 

    Burger, Martin; Dirks, Hendrik; Schönlieb, Carola-Bibiane (Society for Industrial and Applied Mathematics, 2018-01)
    The aim of this paper is to derive and analyze a variational model for the joint estimation of motion and reconstruction of image sequences, which is based on a time-continuous Eulerian motion model. The model can be set ...
  • A gluing operator for the ambitwistor string 

    Roehrig, KA; Skinner, David Benjamin
    We present a new operator in the ambitwistor string which glues together correlators with fewer points or of lower genus. It underpins the recursive construction of tree-level CHY scattering amplitudes by Dolan & Goddard, ...
  • On nonrelativistic 3D spin-1 theories 

    Townsend, Paul Kingsley; Bergshoeff, Eric A; Rosseel, Jan
    We describe non-relativistic limits of the 3D Proca and $\sqrt{\rm Proca}$ theories that yield spin-1 Schroedinger equations. Analogous results are found by generalized null reduction of the 4D Maxwell or complex self-dual ...
