两个曲面乘积的Gromov范数

The Gromov Norm of the Product of Two Surfaces

Lewis Bowen, Jesus A. de Loera, Mike Develin, Francisco Santos

摘要:

本文对两个曲面的笛卡儿积的Gromov范数作了一个估计。我们的方法使用这些规范之间的连接和两个多边形的产品的三角剖分的最小尺寸。这使我们能够证明,当两个因子都有亏格2时,这个乘积的Gromov范数在32和52之间。任意属的情况很容易从这个例子中推导出来。

英文摘要:

We make an estimation of the value of the Gromov norm of the Cartesian product of two surfaces. Our method uses a connection between these norms and the minimal size of triangulations of the products of two polygons. This allows us to prove that the Gromov norm of this product is between 32 and 52 when both factors have genus 2. The case of arbitrary genera is easy to deduce form this one.
