My thesis is that we should not be teaching calculus and linear algebra in first year, rather we should be using those (wonderful) subjects to teach our students what they really want and need (knowledge and skills). That might strike you as a simple change of emphasis, but the more that I have experimented with this, the more I see and try out in my own teaching, the more profound and critical the difference becomes. This is not only a change in pedagogy, it is a change in curriculum. I will talk for some 20 minutes about the experiences that have led me to this conclusion, and what it implies, and will give some examples. I welcome others to come and participate actively in the following discussion. For students and teachers I can offer some support towards registration and travel. Email me at peter.taylor@queensu.ca.

The purpose of this Scientific Session is to bring together specialists and students in these research areas to exchange their results and ideas on topics including homological conjectures, derived categories, covering theory, geometrical characterizations of the representation type of algebras, cluster categories and alike. We expect about 15 speakers from Canada, USA, Mexico and possibly Brazil and Europe. samedi 7 décembre 11:30 - 12:00 Alistair Savage (University of Ottawa), Categorification and Heisenberg doubles arising from towers of algebras, Albert 12:00 - 12:30 Frauke Bleher (University of Iowa), Orbit closures, rational surfaces, and Euler characteristics, Albert 14:00 - 14:30 Benjamin Steinberg (City College, New York), Koszul Algebras associated to zonotopes and CAT(0) cube complexes, Albert 14:30 - 15:00 Markus Schmidmeier (Florida Atlantic University), Box moves on Littlewood-Richardson tableaux, Albert 15:30 - 16:00 Mark Kleiner (Syracuse University), Integrations and functor Ext, Albert 16:00 - 16:30 Frank Marko (Penn State University), Derived representation type of Schur superalgebras, Albert 16:30 - 17:00 Helene Tyler (Manhattan College), String algebras with one cycle - the rhombic picture, Albert 17:00 - 17:30 Charles Paquette (University of Sherbrooke), Homological dimensions of subalgebras, Albert 17:30 - 18:00 Ellen Kirkman (Wake forest University), Twisted Matrix Factorizations, Albert dimanche 8 décembre 9:00 - 9:30 Eleonore Faber (University of Toronto), The global spectrum of commutative rings, Albert 9:30 - 10:00 Calin Chindris (University of Missouri), Moduli spaces of modules of finite-dimensional algebras, Albert lundi 9 décembre 9:00 - 9:30 Joel Kamnitzer (University of Toronto), Representations of quotients of shifted Yangians, Lyon 9:30 - 10:00 Colin Ingalls (University of New Brunswick), Noncommutative Resolutions, Lyon 14:00 - 15:00 Raymundo Bautista (UNAM, Mexico), Lyon Fonctions symétriques et généralisations Org: Angele Hamel (Laurier) et Stephanie van Willigenburg (UBC) samedi 7 décembre  (York) 11:30 - 12:00 Anna Stokke (Winnipeg), Jeu-de-taquin promotion and cyclic sieving for semistandard hook tableaux 12:00 - 12:30 Anna Bertiger (Waterloo), An Equivariant Rim Hook Rule 14:00 - 14:30 Jia Huang (Minnesota), 0-Hecke algebra action on the Stanley-Reisner ring of the Boolean algebra 14:30 - 15:00 Vasu Tewari (UBC), 0-Hecke modules for quasisymmetric Schur functions 15:30 - 16:00 Aaron Lauve (Loyola), Revisiting r-Quasisymmetric Polynomials 16:00 - 16:30 Luis Serrano (UQAM), The immaculate basis of the non-commutative symmetric functions 16:30 - 17:00 Alejandro Morales (UQAM), Bijections and symmetries for factorizations of the long cycle 17:00 - 17:30 Kyle Petersen (de Paul), How to write a permutation as a product of involutions 17:30 - 18:00 Greg Warrington (Vermont), The Sweep Map dimanche 8 décembre  (York) 14:00 - 14:30 Franco Saliola (UQAM), Spectrum of the random-to-random operator 14:30 - 15:00 Sam Hsiao (Bard), Probabilistic interpretations of quasisymmetric functions 15:30 - 16:00 Peter McNamara (Bucknell), Comparing skew Schur functions: a quasisymmetric perspective 16:00 - 16:30 Mathieu Guay Paquet (UQAM), Convex combinations of chromatic symmetric functions 16:30 - 17:00 Holly Heglin (York)
