  • Differential Invariants of Conformal and Projective Surfaces 
    Hubert, E.; Olver, P.J. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We show that, for both the conformal and projective groups, all the differential invariants of a generic surface in three-dimensional space can be written as combinations of the invariant derivatives of a single differential ...
  • Geodesic Flow and Two (Super) Component Analog of the Camassa-Holm Equation 
    Guha, P.; Olver, P.J. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    We derive the 2-component Camassa-Holm equation and corresponding N = 1 super generalization as geodesic flows with respect to the H1 metric on the extended Bott-Virasoro and superconformal groups, respectively.
  • Liouville Correspondences between Integrable Hierarchies 
    Kang, J.; Liu, X.; Olver, P.J.; Qu, C. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    In this paper, we study explicit correspondences between the integrable Novikov and Sawada-Kotera hierarchies, and between the Degasperis-Procesi and Kaup-Kupershmidt hierarchies. We show how a pair of Liouville transformations ...
  • On the Structure of Lie Pseudo-Groups 
    Olver, P.J.; Pohjanpelto, J.; Valiquette, F. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    We compare and contrast two approaches to the structure theory for Lie pseudo-groups, the first due to Cartan, and the second due to the first two authors. We argue that the latter approach offers certain advantages from ...
  • Pohozhaev and Morawetz Identities in Elastostatics and Elastodynamics 
    Bozhkov, Y.; Olver, P.J. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We construct identities of Pohozhaev type, in the context of elastostatics and elastodynamics, by using the Noetherian approach. As an application, a non-existence result for forced semi-linear isotropic and anisotropic ...
