2. 1. Asymptotics of Eigenpolynomials of Exactly-Solvable Operators

   Author : Tanja Bergkvist; Boris Shapiro; Andrei Martinez-Finkelshtein; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; exactly-solvable; eigenpolynomials; zero distribution; asymptotics; MATHEMATICS; MATEMATIK; matematik; Mathematics;

   Abstract : The main topic of this doctoral thesis is asymptotic properties of zeros in polynomial families arising as eigenfunctions to exactly-solvable differential operators. The study was initially inspired by a number of striking results from computer experiments performed by G. Masson and B. Shapiro for a more restrictive class of operators. READ MORE

4. 2. A Class of Renewal Processes in Random Environments

   Author : David Svensson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; point process; renewal process; random environment; coupling; regeneration; failure rate; Poisson embedding; asymptotics; stochastic domination; stochastic monotonicity; renewal process;

   Abstract : This paper deals with a generalization of the class of renewal processes with absolutely continuous life length distribution, obtained by allowing a random environment to modulate the stochastic intensity of the renewal process. The random environment is a birth and death process with a finite state space. READ MORE
