State-dependent Foster–Lyapunov criteria for subgeometric convergence of Markov chains

- Stephen B. Connor, G. Fort
- Mathematics
- 16 January 2009

We consider a form of state-dependent drift condition for a general Markov chain, whereby the chain subsampled at some deterministic time satisfies a geometric Foster-Lyapunov condition. We present… Expand

Optimal co-adapted coupling for the symmetric random walk on the hypercube

- Stephen B. Connor, S. Jacka
- Mathematics
- 8 January 2008

Let X and Y be two simple symmetric continuous-time random walks on the vertices of the n-dimensional hypercube, Z2n. We consider the class of co-adapted couplings of these processes, and describe an… Expand

Correction. Perfect simulation for a class of positive recurrent Markov chains

- Stephen B. Connor, W. Kendall
- Mathematics
- 6 November 2007

In [1] we introduced a class of positive recurrent Markov chains, named tame
chains. A perfect simulation algorithm, based on the method of dominated CFTP,
was then shown to exist in principle for… Expand

Separation and coupling cutoffs for tuples of inde- pendent Markov processes

- Stephen B. Connor
- Mathematics
- 19 February 2008

We consider an n-tuple of independent ergodic Markov processes, each of which converges (in the sense of separation distance) at an exponential rate, and obtain a necessary and sufficient condition… Expand

Mixing times for exclusion processes on hypergraphs

- Stephen B. Connor, Richard Pymar
- Mathematics
- 8 June 2016

We introduce a natural extension of the exclusion process to hypergraphs and prove an upper bound for its mixing time. In particular we show the existence of a constant $C$ such that for any… Expand

Mixing Time and Cutoff for a Random Walk on the Ring of Integers mod $n$

- M. Bate, Stephen B. Connor
- Mathematics
- 14 July 2014

We analyse a random walk on the ring of integers mod $n$, which at each time point can make an additive `step' or a multiplicative `jump'. When the probability of making a jump tends to zero as an… Expand

OPTIMAL CO-ADAPTED COUPLING FOR THE SYMMETRIC

- Stephen B. Connor, S. Jacka

Let X and Y be two simple symmetric continuous-time random walks on the vertices of the n-dimensional hypercube, Z n . We consider the class of coadapted couplings of these processes, and describe an… Expand
