摘要：
We obtain some formulas for t-expansion coefficients of meromorphic Drinfeld modular forms for GL(2)(F-q[T]). Let j(z) be the Drinfeld modular invariant. As an application we show that the values of j(z) at points in the divisor of Drinfeld. modular forms for GL(2)(F-q[T]) are algebraic over F-q(T). (c) 2005 Elsevier Inc. All rights reserved.
