Let q be a power of the prime number p, let , and let be an integer. For points which are -linearly independent, we show that there exist positive constants and such that for each integer and for each generator τ of , we have that for all except values , the corresponding specializations and cannot have orders of degrees less than as torsion points for the Drinfeld module (where is the additive group scheme), given by .

设q是素数p的幂,令, 然后让 是一个整数。对于积分 哪个是 -线性无关,我们证明存在正常数 和 使得对于每个整数 并且对于每个发生器τ的,除了 价值观 , 相应的专业 和 度数不能小于 作为 Drinfeld 模块的扭力点 (在哪里 是附加组方案),由下式给出 .
