The lattice point discrepancy of a body of revolution: Improving the lower bound by Soundararajan's method
摘要:
对于三维欧几里得空间中的凸体B,它在绕一个坐标轴旋转下不变,并且具有有界非零曲率的光滑边界,从下面估计B的线性放大副本的格点差异(整数点数减去体积)。在K. Soundararajan,一个欧米茄界得到的,改善了所有早期的结果,这种。
英文摘要:
For a convex body B in three-dimensional Euclidean space, which is invariant under rotations around one coordinate axis and has a smooth boundary of bounded nonzero curvature, the lattice point discrepancy (number of integer points minus volume) of a linearly enlarged copy of B is estimated from below. On the basis of a recent method of K. Soundararajan, an Omega-bound is obtained that improves upon all earlier results of this kind.
