From asymptotics to spectral measures: determinate versus indeterminate moment problems [PDF]

open access: yes, 2005
In the field of orthogonal polynomials theory, the classical Markov theorem shows that for determinate moment problems the spectral measure is under control of the polynomials asymptotics.

Numerical Approximation of Probability Mass Functions Via the Inverse Discrete Fourier Transform

open access: yes, 2012
First passage distributions of semi-Markov processes are of interest in fields such as reliability, survival analysis, and many others. The problem of finding or computing first passage distributions is, in general, quite challenging.
