A proof of the Proportionality Theorem
J. -P. Brasselet, J. Seade, T. Suwa
Abstract
The purpose of this note is to give a direct and self-contained proof of the Proportionality Theorem of Brasselet-Schwartz. This theorem relates the Schwartz indices of frames obtained by radial extension on Whitney stratified analytic spaces, with the obstructions to extending the canonical lifting of these frames as non-zero sections of the corresponding Nash bundle.
