Moduli space for Riemann surfaces with boundaries and open string loop diagrams
I'm searching for information on the moduli space for Riemann surfaces with boundaries, like the ones used to compute open string loop diagrams. I found a huge lot of info for the case without ...

Topological strings: Why is the complex structure for $T^2$ denoted as $\tau$ in string theory?
In these notes by Vafa on topological string theory he says in page 7 that the moduli of the 2-torus can be repackaged into two quantities:
$$A=iR_1/R_2 \,\,\,\,\,\,\,\,\, \tau=iR_2/R_1$$
where $A$ ...
