Analysis of some exactly solvable diminishing urn models

Combinatorics 2022-12-13 v1 Probability

Abstract

We study several exactly solvable Polya-Eggenberger urn models with a \emph{diminishing} character, namely, balls of a specified color, say xx are completely drawn after a finite number of draws. The main quantity of interest here is the number of balls left when balls of color xx are completely removed. We consider several diminishing urns studied previously in the literature such as the pills problem, the cannibal urns and the OK Corral problem, and derive exact and limiting distributions. Our approach is based on solving recurrences via generating functions and partial differential equations.
