  • Batard, Thomas; Bertalmío, Marcelo (Springer, 2013)
    We introduce a gradient operator that generalizes the Eu- clidean and Riemannian gradients. This operator acts on sections of vector bundles and is determined by three geometric data: a Rieman- nian metric on the base ...
  • Batard, Thomas; Bertalmío, Marcelo (SIAM (Society for Industrial and Applied Mathematics), 2014)
    We present a generalization of the Euclidean and Riemannian gradient operators to a vector bundle, a geometric structure generalizing the concept of manifold. One of the key ideas is to replace the standard differentiation ...
