What I was asking about integration is this: on a compact Riemannian, there is a (smooth) measure described in terms of curvature of the manifold whose total integral is the euler characteristic, but we can also use it as a natural measure on the manifold for integrating other functions. I don't know (and the papers I cited don't say, but I'll check out your paper) a natural "measure" on R whose total integral is -1. Given the Chen/Rota definition, I'd expect it to concentrated near the ends. | |
