摘要

In 1988 Persi Diaconis considered the following random walk on Zn . Pick k values from Zn and then repeatedly choose one of these values at random. This choice determines a random walk starting at 0 and the natural question that arises is, how long does it take the walk to get close to uniformly distributed on Zn for "most" choices of the k values. In 1989 A. Greenhalgh, in his thesis, gave a lower bound for a random walk on Zn . A paper written by J. Dai and M. Hildebrand in 1997 considered random walks on Zn without restrictions on n and in the case where k is a constant. It is important to note that the set of k values were chosen at random but were subject to certain divisibility restrictions. With these restrictions, it will take slightly over n2/(k-1) steps for the position of the typical random walk to be close to uniformly distributed on Zn . Using the same divisibility restriction this thesis will find a similar bound for a random walk on ZpxZ pn where p is a constant.; In 1992 C. Dou considered some cases of the random walk on an abelian group of order n where n is not prime, but instead n = p1··· pt where t is no more than a constant. The p1,···,p t are all prime, with p1 ≥ ··· ≥ pt and p1 ≤ Ap t for some constant A. We will show that if you relax some of the conditions that Dou had on t, m, and A then we can extend his work to include more examples that Dou's restrictions could not.; In 1997 Farid Bassiri in his thesis proved some bounds on a random walk on the dihedral group. This thesis will give a comprehensive study of the random walks on the dihedral group generated by a k-subset.

Hildebrand在1997年发表的一篇论文中考虑了在Zn上的随机游动而对n没有限制,并且在k为常数的情况下。重要的是要注意,这组k值是随机选择的,但受到某些除数限制。在这些限制下,典型随机游走的位置要接近均匀分布在Zn上,将花费n2 /(k-1)个步骤。使用相同的除数限制,本文将找到ZpxZ pn上随机游动的相似边界,其中p为常数。在1992年,C。Dou考虑了在n阶不是素数的n个阿贝尔群上随机游动的某些情况,而是n = p1···pt,其中t不大于常数。 p1,···,pt都是素数,对于某些常数A,p1≥···≥pt和p1≤Ap t。我们将证明,如果您放宽Dou在t,m和然后,我们可以扩展他的工作,以包含窦先生的限制无法提供的更多示例。 1997年,Farid Bassiri在他的论文中证明了二面体组随机行走的某些界限。本文将对由k子集生成的二面体组的随机游动进行全面研究。
