Sept 2	Lucas Gagnon (York), Anthony Aurthur Lazzeroni Jr (HKBU), Farhad Soltani (York), Nantel Bergeron (York)	First Meeting. Icebreaker and Problem Suggestions A few people will present some icebreaker talks and suggest some open problems.
Sept 9	Farhad Soltani (York)	DQSYM I will be talking about quasisymmetric polynomials on two sets of variables and the coinvariant space.
Sept 16	Lucas Gagnon (York)	Chromatic quasisymmetric functions and representation theory This talk will explore several topics related to the chromatic symmetric function and its quasisymmetric q-analogue. First, I will use them as a way to reviewt (quasi-)symmetric functions and some of their properties. Then, I will talk about some representation theoretic interpretations for symmetric functions generally, and the chromatic quasisymmetric function in particular.
Sept 23	Anthony Aurthur Lazzeroni Jr (HKBU)	The ideal of r-quasisymmetric functions In this talk I will recall the space of r-quasisymmetric functions. These spaces are nested subHopf algebras that interpolates between the space of Quasisymmetric functions and Symmetric functions. I will also discus some previous results about the quotient ring of the polynomial ring and the ideal generated by non-constant homogenous quasisymmetric functions.
