We investigate large deviations for the empirical measure of the forward and backward recurrence time processes associated with a classical renewal process with arbitrary waiting-time distribution. The Donsker-Varadhan theory cannot be applied in this case, and indeed it turns out that the large deviations rate functional differs from the one suggested by such a theory. In particular, a non-strictly convex and non-analytic rate functional is obtained. 
Large deviation principles for the finite-dimensional distributions of compound renewal processes
The paper deals with the large deviation probabilities for compound renewal processes. We establish the local and “integral” principles of large deviations in the state space of the process (i.e. for
Large deviations for the empirical measure of heavy-tailed Markov renewal processes
Abstract A large deviations principle is established for the joint law of the empirical measure and the flow measure of a Markov renewal process on a finite graph. We do not assume any bound on the
The Large Deviation Principle for Finite-Dimensional Distributions of Multidimensional Renewal Processes
We study two types of multidimensional compound renewal processes (c.r.p.). We assume that the elements of the sequences that control the processes satisfy Cramer’s moment condition. Wide conditions
Precise large deviations of aggregate claims in a risk model with size dependence and non stationary arrivals
ABSTRACT Consider a risk model with claims of heavy tails for non stationary arrival processes that satisfy a large-deviation principle. Assume that the claim sizes and interarrival times form a
A renewal version of the Sanov theorem
Large deviations for the local time of a process X( t) are investigated, where X(t)=xi for t∈[Si-1,Si[ and (x_j) are i.i.d. random variables on a Polish space, S_j is the j-th arrival time of a
Large deviations for Lotka-Nagaev estimator of a randomly indexed branching process
Consider a continuous time process {Yt = ZNt , t ≥ 0}, where {Zn} is a supercritical Galton– Watson process and {Nt} is a renewal process which is independent of {Zn}. Firstly, we study the
Large deviation principles for cumulative processes and applications
The aim of this paper is to prove a Large Deviation Principle (LDP) for cumulative processes also known as coumpound renewal processes. These processes cumulate independent random variables occuring
Large Time Asymptotic of Heavy Tailed Renewal Processes
We study the large-time asymptotic of renewal-reward processes with a heavy-tailed waiting time distribution. It is known that the heavy tail of the distribution produces an extremely slow dynamics,
Large deviation principles for renewal-reward processes
We establish a sharp large deviation principle for renewal-reward processes, supposing that each renewal involves a broad-sense reward taking values in a real separable Banach space. In fact, we
Donsker-Varadhan asymptotics for degenerate jump Markov processes
We consider a class of continuous time Markov chains on a compact metric space that admit an invariant measure strictly positive on open sets together with absorbing states. We prove the joint large


Large deviations behavior of counting processes and their inverses
It is shown that embedded regenerative structure is sufficient for the counting process or its inverse process to have exponential asymptotics, and thus satisfy the Gärtner-Ellis condition.
Large deviations for occupation times of Markov processes with L2 semigroups
Our aim is to unify and extend the large deviation upper and lower bounds for the occupation times of a Markov process with L 2 semigroups under minimal conditions on the state space and the process
Large Deviations for Empirical Measures of Not Necessarily Irreducible Countable Markov Chains with Arbitrary Initial Measures
All known results on large deviations of occupation measures of Markov processes are based on the assumption of (essential) irreducibility. In this paper we establish the weak* large deviation

Large deviations of the current in stochastic collisional dynamics
We consider a class of deterministic local collisional dynamics, showing how to approximate them by means of stochastic models and then studying the fluctuations of the current of energy. We show
The Large Deviations of random time-changes
This thesis is concerned with the transformation of the Large Deviation properties of a stochastic process under a random time-change. A random time-change is the reparametrisation of a process by a
Uniformly Integrable Operators and Large Deviations for Markov Processes
Abstract In this paper we introduce and investigate the notion of uniformly integrable operators on L p ( E , μ ). Its relations to classical compactness and hypercontractivity are exhibited. Several
Some Useful Functions for Functional Large Deviations
Useful descriptions of stochastic models are often provided when they are represented as functions of well understood stochastic models. Properties of the well understood model can be preserved by
