| Research Abstract |
Given a Markov process X with a weak dual process and countable boundary points, all possible Markovian extensions of X beyond its life time preserving the weak duality are characterized in terms of intrinsic quantities for X called Feller measures and independent parameters of killing and jumps on the boundary. Such an extension of X is constructed by repeating one point extensions by means of Poisson point processes of excursions.
