DESCRIPTION:Through   the mathematical construction of finite element meth
 ods\, the &ldquo\;standard&rdquo\;   finite element method will often pres
 erve the underlying symmetry of a given   differential equation. However\,
  this is not always the case\, and while   historically much attention has
  been paid to the preserving of conserved   quantities the preservation of
  Lie symmetries is an open problem. We   introduce a methodology for the d
 esign of arbitrary order finite element   methods which preserve the under
 lying Lie symmetries through an equivariant   moving frames based invarian
 tization procedure.
