3rd order mock theta functions

introduction

 

• \(f(q) = \sum_{n\ge 0} {q^{n^2}\over (-q;q)_n^2} = {2\over \prod_{n>0}(1-q^n)}\sum_{n\in Z}{(-1)^nq^{3n^2/2+n/2}\over 1+q^n}\)

• \Thate(24z)=q-5q^25+7q^{49}-11q^{121}+13q^{169}-\cdots
• M_f(z)=q^{-1}f(q^24)+\frac{i}{\sqrt{3}}\int_{}^{}\frac{\Theta(24z)}{}dz

• the asymptotic series for coefficients of the order 3 mock theta function f(q) studied by of (Andrews 1966) and Dragonette (1952) converges to the coefficients (Bringmann & Ono 2006).
• In particular Mock theta functions have asymptotic expansions at cusps of the modular group, acting on the upper half-plane, that resemble those of modular forms of weight 1/2 with poles at the cusps.
