Speaker: Valentin Lychagin
Title: Invariants of projective -actions and their application to recognition of fingerprints
Abstract:
We study the field of rational differential invariants of the left -action on the homogeneous space and use them to give an alternative description of the shape space and fingerprints, introduced by Mumford and Sharon.
