双分散随机球填充上的拓扑和几何随机游动

Topological and Geometrical Random Walks on Bidisperse Random Sphere Packings

Peter Hinow

摘要:

由一个制药科学问题引起的动机[B]。Baeumer等人,Discr.康丁Dyn. Sys. B12]中,研究了双分散随机球填充的接触图上的随机游动.对于在指定目标集终止的未加权图上的随机游动,我们比较了步数和游动的总欧氏长度。我们发现这两个度量之间的线性关系,可以从接触图的边长概率计算出的比例常数。

英文摘要:

Motivated by a problem arising from pharmaceutical science [B. Baeumer et al., Discr. Contin. Dyn. Sys. B 12], we study random walks on the contact graph of a bidisperse random sphere packing. For a random walk on the unweighted graph that terminates in a specified target set, we compare the number of steps and the total euclidean length of the walk. We find a linear relationship between the two metrics with a proportionality constant that can be calculated from the edge length probabilities of the contact graph.
