Periods, Coupling Constants and Modular Functions in N=2 SU(2) SYM with Massive Matter
We determine the mass dependence of the coupling constant for N=2 SYM with $N_f=1,2,3$ and $4$ flavours. All these cases can be unified in one analytic expression, given by a Schwarzian triangle function. Moreover we work out the connection to modular functions which enables us to give explicit form...
