Connes trace formula $$ \mathrm{Tr}\,{U(h)}=2h(1)\ln\Lambda + \sum_{v} \int d^{*}x \frac{h(u^{-1})}{|1-u|} $$

Weil's trace $$ \int_{C}h(u)|u|d^{*}u- \sum_{\rho}\int_{C}h(u)|u|^{\rho}d^{*}u+\int_{C}h(u)d^{*}u=\sum_{v} \int d^{*}x \frac{h(u^{-1})}{|1-u|} $$

in both cases the right side is quite similar. But are these two traces equivalent?

You might want to give more context. For example, in what circumstances are these trace formulae being used? And could you define at least some of the notation being used? – M Turgeon Aug 12 '12 at 16:15
