Conformal projective invariants in the problem of image recognition.

Abstract

In this paper we reduce local classification of differential 1-forms on the plane with respect to group SL_2(C) of Mobius transformations. We find the field of rational conformal differential invariants and show that the field is generated by two differential invariant derivations and by differential invariants of the first and second orders.
