А. creator: Rodríguez-Dagnіno, Ramón М. subject: Mathematical Analysis description: In this paper we study a one-dimensional random motion by having a general Erlang distribution for the sojourn times and we obtain higher order hyperbolic equations for this case. We apply the methodology of random evolutions to ¯nd the partial di®erential equations governing the particle motion and we obtain a factorization of these equations. As a particular case we ¯nd the linear biwave equation for the symmetric motion case and 2-Erlang distributions for the sojourn times of a semi-Markov evolution. publisher: ROSE date: 2005 type: Article type: PeerReviewed format: text language: uk identifier: http://eprints.zu.edu.ua/13382/1/ROSE_2005.pdf identifier: Pogoruі, А.
