Abstract

There are many instances known when the Fourier coefficients of modular forms are congruent to partial sums of hypergeometric series. In our previous work arXiv:1803.01830, such partial sums are related to the radial asymptotics of infinite qq-hypergeometric sums at roots of unity. Here we combine the two features to construct a hypergeometric qq-deformation of two CM modular forms of weight 3 and discuss the corresponding qq-congruences.
