✦ Synopsis

In this paper we consider some Kolmogorov -Feller equations with a small parameter h.

We present a method for constructing the exact (exponential) asymptotics of the fundamental solution of these equations for finite time intervals uniformly with respect to h. This means that we construct an asymptotics of the density of the transition probability for discontinuous Markov processes. We justify the asymptotic solutions constructed. We also present an algorithm for constructing all terms of the asymptotics of the logarithmic limit (logarithmic asymptotics) of the fundamental solution as t β†’ +0 uniformly with respect to h. We write formulas of the asymptotics of the logarithmic limit for some special cases as t β†’ +0. The method presented in this paper also allows us to construct exact asymptotics of solutions of initial -boundary value problems that are of probability meaning.

The dependence comes from the assumption that claim arrivals of the two classes are governed by a common renewal counting process. We study two types of ruin in the two-dimensional framework.

In many long-term chronic diseases, patients pass through an observable sequence of ordered clinical states as their condition progressively worsens. Often the information on which disease state the patient is in is incompletely recorded, usually with information only available on the occasion of a
