收缩Riemann surfaces上的Bergman核

Bergman kernels on punctured Riemann surfaces

Hugues Auvray, Xiaonan Ma, George Marinescu

摘要:

本文考虑一个在穿孔附近具有与Poincaré度量相等的Hermite度量的穿孔Riemann曲面和一个极化该度量的全纯线丛。我们证明了Bergman核可以局部化在奇点周围,其局部模型是被赋予标准Poincaré度量的穿孔单位圆盘的Bergman核。作为结果,我们得到了Bergman核的上确界范数的最优一致估计,涉及张量幂幂的分数增长阶。

英文摘要:

In this paper we consider a punctured Riemann surface endowed with a Hermitian metric which equals the Poincaré metric near the punctures and a holomorphic line bundle which polarizes the metric. We show that the Bergman kernel can be localized around the singularities and its local model is the Bergman kernel of the punctured unit disc endowed with the standard Poincaré metric. As a consequence, we obtain an optimal uniform estimate of the supremum norm of the Bergman kernel, involving a fractional growth order of the tensor power.
