This paper is devoted to studying the long-term behaviour of a continuous-time Markov chain that can be interpreted as a pair of linear birth processes which evolve with a competitive interaction; as a special case, they include the famous Lotka–Volterra interaction. Another example of our process is related to urn models with ball removal. We show that, with probability one, the process eventually escapes to infinity by sticking to the boundary in a rather unusual way.

Long term behaviour of two interacting birth-and-death processes
TLDR
The long term evolution of a continuous time Markov chain formed by two interacting birth-and-death processes is studied and it is found that in some of these cases the Markov chains escapes to infinity in an unusual way, and the corresponding trajectories can be rather precisely described.
Long Term Behaviour of Locally Interacting Birth-and-Death Processes
In this paper we study long-term evolution of a finite system of locally interacting birth-and-death processes labelled by vertices of a finite connected graph. A detailed description of the
Long Term Behaviour of a Reversible System of Interacting Random Walks
TLDR
It is shown that the system undergoes phase transitions, with different behaviour in various regions, depending on model parameters and properties of the underlying graph, as well as the complete classification of the long-term behaviour of the corresponding continuous time Markov chain.

Angular asymptotics for multi-dimensional non-homogeneous random walks with asymptotically zero drift
We study the rst exit time from an arbitrary cone with apex at the origin by a non-homogeneous random walk (Markov chain) on Zd (d 2) with mean drift that is asymptotically zero. Specically, if the
Continuous-Time Markov Chains
Continuous time Markov chains have steady state probability solutions if and only if they are ergodic, just like discrete time Markov chains. Finding the steady state probability vector for a
