"Degree invariant functions and Martin's Conjectures"

We will continue the proof we started for the special case of Martin's conjecture.  That special case result says: Assuming the Axiom of Determinacy, a uniformly degree invariant function that is not increasing on a cone must be constant on a cone.

We will study a class of compact quantum groups whose structure and representation theory depend on the combinatorics of set partitions, and we will also study some "noncommutative spaces" on which these quantum groups act.  The emphasis of the presentations will be placed on the illustrative examples provided by the quantum permutation group and by the free orthogonal quantum group.
