A Probabilistic Characterization of the Dominance Order on Partitions
Clifford Smyth
A probabilistic characterization of the dominance partial order on the set of partitions is presented. This extends work in "Symmetric polynomials and symmetric mean inequalities".…
Revolutionaries and spies on trees and unicyclic graphs
Daniel W. Cranston, Clifford D. Smyth, Douglas B. West
A team of {\it revolutionaries} and a team of {\it spies} play a game on a graph . Initially, revolutionaries and then spies take positions at vertices. In each subseque…
