This collection honors Ron Doney’s work and includes invited articles by his collaborators and friends. After an introduction presenting Ron Doney’s work and how it has influenced the field, the papers will cover both discrete-time processes, with random walks and derivatives thereof, and continuous-time processes, including Lévy processes and diffusions. Whilst the field of Lévy processes and random walks with their applications is vast, a good number of contributions will focus around the classical fluctuation theory and its ramifications that Ron Doney is best known for.weiterlesen
