You're right. Sorry for not knowing the correct terminology ... Corrected.

Hmm, I don't think so. for k=4, aren't the "two points" of type $C^4/Z_2$ identified by the $Z_4$ action? Similarly for $k=6$. Anyway, the configurations of the fixed points follow the length of the legs of Dynkin diagrams of $D_4$, $E_{6,7,8}$, and constrained by the fact that 1/2+1/2+1/2+1/2=1/3+1/3+1/3=1/4+1/4+1/2=1/6+1/3+1/2=1 ...

comment Question on Atiyah-Patodi-Singer on $T^3$
If my computation is OK, I think the answer is no. I guess I need to ask Edward what he meant.

comment Question on Atiyah-Patodi-Singer on $T^3$
Well, Witten says so in p.47 of arxiv.org/abs/hep-th/0006010 . Yes I knew I shouldn't trust what's written in physicists' papers...
