摘要：

For a prime p 3 (mod 4) and m >= 2, Romik raised a question about whether the Taylor coefficients around root-1 of the classical Jacobi theta function.3 eventually vanish modulo p(m). This question can be extended to a class of modular forms of half-integral weight on Gamma(1)(4) and CM points; in this paper, we prove an affirmative answer to it for primes p >= 5. Our result is also a generalization of the results of Larson and Smith for modular forms of integral weight on SL2(Z).
