In this talk, I will share my experiences working in data science related roles in Hong Kong and Canada. I will describe how I explored different career paths and possibilities during my studies, despite starting with a weak academic background in...

Schoen and Yau proved the positive mass theorem on asymptotically flat manifolds with non-negative scalar curvature. Since then, several quasilocal masses have been proposed to describe the energy of compact domains. On the other hand, Gromov asked...

Please note, the instructor will not be available for the session session on December 8th, so it has been cancelled. Students of grades 5 to 7 are invited to challenge and develop their thinking and creativity skills at the Math Circle Workshops...

John Pardon has recently proved the Gromov-Witten Donaldson-Thomas correspondence using a new homology/cohomology machinery for 1-cycles in 3-folds. We study a much simplified version, namely for 0-cycles (points) in curves. In this case the theory...

Roughly speaking, outbreaks of respiratory infections, such as measles, CoViD-19, and influenza, are shaped by two main factors: (1) the patterns and nature of contacts between individual hosts, and (2) the distribution of immunity locally and...

We investigate the sums of reciprocals to an arithmetic progression taken modulo one, that is sums of fractional parts 1/{na−y}, where a,y are real parameters. Such upper bounds are known in the literature, with many applications in number theory...

A classical problem in combinatorial geometry, posed by Erd\H{o}s in 1946, asks to determine the maximum number of unit segments in a set of $n$ points in the plane. Since then a great variety of extremal problems in finite point sets have been...

In this talk, we study cut-generating functions in the setting of the Gomory-Johnson group relaxations for integer programming. We address an open question: whether every facet (extreme function) for a finite cyclic group relaxation injects into the...

Iteration has revealed mathematical structure for millennia—from ancient Babylonian root-finding techniques to the intricate fractals developed by Fatou and Julia during the First World War. Yet many mysteries remain. One such puzzle centers on...
