Long time ago I studied math finishing with a PhD. While they are old and most likely not interesting for anyone here are the scientific papers (published and unpublished) that were the outcome.

A Large Deviation Principle for Polynomial Hypergroups was published in the Journal of the Lonfdon Mathematical Society.

Large Deviations on One Dimensional Hypergroups

Local limit_theorems for Markov chains associated with disk polynomials

Local limit theorems for Markov chains on a class_of_polynomial_hypergroups

My PhD Thesis in German
