Geometric Invariants of Cuspidal Edges
Printed: Apr 2016
We give a normal form of the cuspidal edge
which uses only diffeomorphisms on the source
and isometries on the target.
Using this normal form, we study differential
geometric invariants of
cuspidal edges which determine them up to order three.
clarify relations between these invariants.
