Spectral analysis of Jacobi operators generated by Markov Birth and Death Processes

Some particular examples of Jacobi Operators (tridiagonal matrices) with growing entries related to the Markov processes will be considered.

Using a Levinson's type theorems approach we plan to determine the spectral structure of the corresponding operators.

No preliminary knowledge of Jacobi Matrices or Orthogonal Polynomials to be required.
