Bonjour Other problem : At the top fo page 9 , line 2 , at the end of theorem 1.4 , il appears to me that i = 1,...,N and not i = 1,...,n . In this theorem, we have alpha(t_i) (partitions of the curve) Cordialement Jean Pellegri "rip pelletier" <bitbucket at comcast.net> a écrit dans le message de news: do3lkh$o22$1 at smc.vnet.net... > In article <dnv48c$och$1 at smc.vnet.net>, > "Steven T.
