Query: R\'enyi Divergence in General Hidden Markov Models   In this paper, we examine the existence of the R\'enyi divergence between two
time invariant general hidden Markov models with arbitrary positive initial
distributions. By making use of a Markov chain representation of the
probability distribution for the general hidden Markov model and eigenvalue for
the associated Markovian operator, we obtain, under some regularity conditions,
convergence of the R\'enyi divergence. By using this device, we also
characterize the R\'enyi divergence, and obtain the Kullback-Leibler divergence
as {\alpha} \rightarrow 1 of the R\'enyi divergence. Several examples,
including the classical finite state hidden Markov models, Markov switching
models, and recurrent neural networks, are given for illustration. Moreover, we
develop a non-Monte Carlo method that computes the R\'enyi divergence of
two-state Markov switching models via the underlying invariant probability
measure, which is characterized by the Fredholm integral equation.
