Strong transience for one-dimensional Markov chains with asymptotically zero drifts
Chak Hei Lo, Mikhail V. Menshikov, Andrew R. Wade
For near-critical, transient Markov chains on the non-negative integers in the Lamperti regime, where the mean drift at decays as as , we quantify degree of…
Functional limit theorems for random walks
Chak Hei Lo, James McRedmond, Clare Wallace
We survey some geometrical properties of trajectories of -dimensional random walks via the application of functional limit theorems. We focus on the functional law of large numb…
On some random walk problems
Chak Hei Lo
In the first part of this thesis, we study a Markov chain on , where is the non-negative real numbers and is a finite set, in which when t…
On the centre of mass of a random walk
Chak Hei Lo, Andrew R. Wade
For a random walk on we study the asymptotic behaviour of the associated centre of mass process . For lattice distributions we g…
