I am working on Zweibach's

I know that x = 0 is one of the fixed points, but the other alludes me. Just a guess, is it the center? but that is

Thanks in advance,

__First Course in String Theory__and question 2.4 asks: Show that there are two points on the circle that are left fixed by the**Z**2 action. (For those without the text, the circle is the space -1 < x <= +1, identified by x ~ x + 2. And the**Z**2 mod imposes the x ~ -x identification on the circle.)I know that x = 0 is one of the fixed points, but the other alludes me. Just a guess, is it the center? but that is

*not*in the fundamental domain!*...eek!*Thanks in advance,
