We show that the absolute value of an invertible holomor- phic function f on the Drinfeld symmetric space is constant on fibers of the building map to the Bruhat–Tits building . Its logarithm is an affine map on the realization of . These results are used to study the vanishing loci of modular forms (coefficient forms, Eisenstein series, para-Eisenstein series) and to determine their images in .

关于更高阶 II 的 Drinfeld 模形式
我们证明绝对值 Drinfeld 对称空间上的可逆全纯函数f 在建筑物映射到 Bruhat-Tits 建筑物的纤维上是恒定的 . 它的对数 是实现的仿射图 . 这些结果用于研究模形式(系数形式、爱森斯坦级数、对爱森斯坦级数)的消失轨迹并确定它们在.
