Linear relations and congruences for the coefficients of Drinfeld modular forms (Q940762)

In analogy with a recent result on modular forms for \(\text{SL}_2({\mathbb Z})\) by \textit{Y. Choie, W. Kohnen} and \textit{K. Ono} [Bull. Lond. Math. Soc. 37, 335--341 (2005; Zbl 1155.11325)], the author derives congruences for the \(t\)-expansion coefficients of Drinfeld modular forms for \(\text{GL}_2({\mathbb F}_q[T])\) and all linear relations among the initial coefficients. The precise statements are slightly too technical to be reproduced here.
