A basis for the space of weakly holomorphic Drinfeld modular forms for GL(2)(A)

초록

We construct a canonical basis for the space of weakly holomorphic Drinfeld modular forms. And we find that the basis elements satisfy a generating function and the duality among coefficients of the basis elements. Moreover we obtain the congruence properties of t-expansion coefficients of these functions under some conditions. (c) 2019 Elsevier Inc. All rights reserved.
