Residues of Chern-Maslov classes: Dedicated to Professor Tatsuo Suwa on his sixtieth birthday

摘要

We describe a localization theory for Maslov classes associated with two Lagrangian subbundles in a real symplectic vector bundle and give a definition of the residue of the Maslov classes. We also compute explicitly the residue of the first Maslov class in the case that the non-transversal set of the two Lagrangian subbundles have codimension 1.
