Title of
Moving Frames for Laplace Invariants. General Case.

Using the methods of regularized moving frames of Fels and Olver we obtained in our ISSAC'08 paper generating sets of invariants for the second- and third-orders bivariate hyperbolic and non-hyperbolic LPDOs. Now we generalize the method to the case of arbitrary order (hyperbolic and non-hyperbolic) LPDOs. A special choice of the normalization equations was invented, so that we were able prove some invariants form a finite (small) generating set of invariants.
