提出了对随机 Laguerre 曲面细分(著名的 Voronoi 曲面细分的加权概括)的系统研究。我们证明,在第三维及更高维度上具有凸单元的每个正常镶嵌都是拉盖尔镶嵌。然后详细研究由平稳标记泊松过程生成的曲面细分。对于这些镶嵌,我们获得了典型 k 面的几何特征和密度的积分公式。我们提出了线性接触分布函数的公式,并证明了 Laguerre 收敛到 Poisson-Voronoi 曲面细分的各种极限结果。随后对平面情况下所获得的积分公式进行数值评估,证明其在实际目的中的适用性。
A systematic study of random Laguerre tessellations, weighted generalisations of the well-known Voronoi tessellations, is presented. We prove that every normal tessellation with convex cells in dimension three and higher is a Laguerre tessellation. Tessellations generated by stationary marked Poisson processes are then studied in detail. For these tessellations, we obtain integral formulae for geometric characteristics and densities of the typical k-faces. We present a formula for the linear contact distribution function and prove various limit results for convergence of Laguerre to Poisson-Voronoi tessellations. The obtained integral formulae are subsequently evaluated numerically for the planar case, demonstrating their applicability for practical purposes.
