Mathematics, applied mathematics and statistics’ Nick Gurski presents to Canadian Mathematical Society

Nick Gurski, assistant professor in the Department of Mathematics, Applied Mathematics and Statistics, presented “Sign conventions, higher supergeometry, and the two-type of the sphere” at the summer meeting of the Canadian Mathematical Society.

About the presentation

Supersymmetry, as studied by theoretical physicists, proposes a host of undiscovered particles, but the mathematics behind it are well-established including the Koszul sign rule, which requires inserting negative signs when performing certain calculations. A universal object coming from algebra, topology or category theory—the focus of Gurski’s presentation—can explain these signs.
