Query: Symmetries and conservation laws for a generalization of Kawahara
  equation   We provide a complete classification of generalized and formal symmetries and
local conservation laws for an evolution equation which generalizes the
Kawahara equation having important applications in the study of plasma waves
and capillary-gravity water waves. In particular, we show that the equation
under study admits no genuinely generalized symmetries and has only finitely
many local conservation laws, and thus this equation is not symmetry
integrable.
