Given my responsibilities as Chair of Glendon's Mathematics Department and as Chair of York University's Senate, I teach only one course in 2021-22, namely
Winter 2022 GL/MATH 1950 3.00 Mathematics of Investment I Wednesdays 18h30-21h30.
Dynamical systems, ergodic theory, thermodynamic formalism, and fractal geometry.
