I like the approximative approach and will definitely try that out. Ideally however I would like to have the function in an exact (or close to) form since I'm going to use it in quite precise calculations. I've tried to compile the function starting from the definition according to Compile[{x, y, z}, Sum[n^2*Exp[-n^2*(1/z - 1)^\[Alpha]*(1 - y) - m^2 (1/z - 1)^\[Alpha]*(1 - x) - 2*n*m (1/z - 1)^\[Alpha]*(-1 + x + y)], {n, -Infinity, Infinity}, {m, -Infinity, Infinity}]] but I'm having trouble integrating that as well. Any thoughts?
