It is shown that sequences of generalized semi-Markov processes converge in the sense of weak convergence of random functions if associated sequences of defining elements (initial distributions, transition functions and clock time distributions) converge. This continuity or stability is used to obtain information about invariant probability measures. It is shown that there exists an invariant p...

The distribution of extrema and overjump functionals for the semi-continuous processes (processes that intersect positive or negative level continuously) on a Markov chain were considered by many authors( for instance, see [1] [3]). In the paper [4] the distribution of extrema for almost semi-continuous processes were treated (the processes that intersect positive or negative level by exponenti...
