我们定义了s∈C的扭曲爱森斯坦级数Es±(h,k;τ),并证明了它们的关联周期函数如何在复平面h的上半部分具有解析延拓到所有C′:=C∈R≤0。我们也使用这个结果,以及各种zeta函数的性质,来证明某些cotan - zeta和的行为类似于(复)权s的量子模形式。
We define twisted Eisenstein series Es±(h,k;τ) for s∈C , and show how their associated period functions, initially defined on the upper half complex plane H , have analytic continuation to all of C′:=C∖R⩽0 . We also use this result, as well as properties of various zeta functions, to show that certain cotangent‐zeta sums behave like quantum modular forms of (complex) weight s .
