 Congruences for coefficients of Drinfeld modular forms Bull. Korean Math. Soc. 2009 Vol. 46, No. 2, 229-234 https://doi.org/10.4134/BKMS.2009.46.2.229Printed March 1, 2009 SoYoung Choi Dongguk University Abstract : We find congruences for the $t$-expansion coefficients of a Drinfeld modular form for $\Gamma_{0}^{+}(Q)$, where $Q$ is a monic irreducible polynomial. As an application we obtain new congruence relations for the $t$-expansion coefficients of Drinfeld modular forms for $GL_{2}(\Bbb{F}_{q}[T])$.
