SUMMARY
A continuous-time Markov chain (CTMC) is classified as recurrent if its embedded discrete-time Markov chain (DTMC) is also recurrent. However, it is established that a positive recurrent CTMC can have a null recurrent DTMC, and vice versa. This relationship highlights the complexities in the behavior of Markov chains, particularly in the context of their return times. An example illustrating this phenomenon is requested for further clarity.
