Oct 31, 2013 at 21:45 comment added Gabrielle I think you are right, thanks very much.
Oct 31, 2013 at 21:39 comment added Mark Opitz A 1-cocycle is just a derivation. Hence $\alpha(\tau)=g\alpha(s) + (1-\tau)\alpha(g)$. Here $\tau \mapsto (1-\tau)\alpha(g)$ is an inner derivation (=1-coboundary). Perhaps Weiss' equation has to be understood "modulo a coboundary" ?
Oct 31, 2013 at 15:44 comment added Gabrielle $\alpha$_s = $\alpha$(s)
Oct 29, 2013 at 20:58 comment added Boris Novikov Which page in Weiss?
Oct 29, 2013 at 19:39 comment added Mark Opitz What is $\alpha_s$ resp. $\alpha_\tau$ ?
