comment Does every inner product fail to turn $C[0,1]$ into a Hilbert space?
@DanielFischer: Thank you very much for the idea in your comment. Yes, I would be interested in the case that the inner product on $C[0,1]$ gives an equivalent topology as the sup norm on $C[0,1]$, but I forgot to clarify this, when typing the question...sorry...

comment 3 Questions concerning the fundamental group of $S^1\vee S^1\vee S^1$
Thanks for the comment. I always thought that the bouquet of 3 circles coincides with a rose with three petals, but $S^1\vee S^1\vee S^1$ can be thought as three circles, that are glued together, but that there are 2 gluing ponits...is that not correct?
