Mixing time bounds for edge flipping on regular graphs

Yunus Emre Demirci, Ümit Işlak, Alperen Özdemir

The edge flipping is a non-reversible Markov chain on a given connected graph, which is defined by Chung and Graham. In the same paper, its eigenvalues and stationary distributions…

Random decompositions of Eulerian statistics

Alperen Y. Özdemir

This paper develops methods to study the distribution of Eulerian statistics defined by second-order recurrence relations. We define a random process to decompose the statistics ov…

On an alternative sequence comparison statistic of Steele

Ümit Işlak, Alperen Y. Özdemir

The purpose of this paper is to study a statistic that is used to compare the similarity between two strings, which is first introduced by Michael Steele in 1982. It was proposed a…
