InvariantSurfaceCondition[symmetry, dependentVariables]
gives the invariant surface condition for the supplied symmetry.
  • The symmetry is represented by an infinitesimal generator. The space of the depedent variables is given in the second argument.
  • dependentVariables can be either one function or a list of functions.
  • InvariantSurfaceCondition gives a linear partial differential equation or a system of linear partial differential equations, known to the Lie theory as the Invariant Surface Conditions.
