The project originated from our joint work on the large deviations for the famous birth-death processes. Some generalizations of the obtained results is one of the goals of this project. We also want to understand how the form of the rate function changes depending on an asymptotic behavior of intensities of the process. Recent works and discussions about large deviations for Markov processes lead us to an ideia to include and develop in the project an alternative, to the Feng & Kurtz large deviation program, and more simple way of proving the large deviations for Markov processes and functionals of them.
