  • Lie Symmetries and Criticality of Semilinear Differential Systems 
    Bozhkov, Y.; Mitidieri, E. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We discuss the notion of criticality of semilinear differential equations and systems, its relations to scaling transformations and the Noether approach to Pokhozhaev's identities. For this purpose we propose a definition ...
  • 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 ...
