We establish the relation among them and prove/reprove formulas relating the total sum of these invariants to some global invariants of the foliation and the invariant curve.Department of Mathematics, Hokkaido University1996-04-01engdepartmental bulletin paperVoRhttps://doi.org/10.14943/83480http://hdl.handle.net/2115/6908410.14943/83480Hokkaido University Preprint Series in Mathematics334111https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/69084/1/pre334.pdfapplication/pdf586.71 KB1996-04-01
