Background:

The Chapman-Kolmogorov equation is fundamental for describing the evolution of probability distributions in stochastic processes.
Jumping processes, like the kangaroo process, exhibit discrete state changes and require specific analytical methods.

Purpose of the Study:

To derive a general solution to the Chapman-Kolmogorov equation for the kangaroo process.
To analyze a special case involving algebraic dependencies.
To investigate the limiting behavior and stationary distributions of the process.

Main Methods:

Derivation of a general solution for the Chapman-Kolmogorov equation.
Analysis of algebraic dependencies within the process.
Development of asymptotic formulas for probability distributions.
