Query: Mock theta functions and weakly holomorphic modular forms modulo 2 and 3   We prove that the coefficients of certain mock theta functions possess no
linear congruences modulo 3. We prove similar results for the moduli 2 and 3
for a wide class of weakly holomorphic modular forms and discuss applications.
This extends work of Radu on the behavior of the ordinary partition function
modulo 2 and 3.
