I am working on Zweibach's 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 Z2 action. (For those without the text, the circle is the space -1 < x <= +1, identified by x ~ x + 2. And the Z2 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,
