Students of grades 5 to 7 are invited to challenge and develop their thinking and creativity skills at the Math Circle Workshops. This is an enrichment program for students organized by the faculty members of the Department of Mathematics at the...

Stoichiometric principles provide a rigorous, law-based backbone for building mechanistic models that are robust and empirically testable through conservation and physiological constraints. In this talk, I will introduce stoichiometric models that...

A c-colouring of a combinatorial design is an assignment of colours, chosen from a set of size c, to the points of the design. A c-colouring is equitable if every block of size k contains ⌊k/c⌋ or ⌈k/c⌉ points of each colour. In 2016, Luther and Pike...

Let C be a class of algebraic structures. For example, C could be a class of quadratic forms, field extensions or algebraic curves of a given genus. To measure the complexity of C, mathematicians ask a natural question: how many algebraically...

Tensor triangular geometry associates a rich geometric structure, the spectrum, to a “nice” category where one can add, subtract and multiply objects. Examples include modules over a commutative ring and representations of a finite group. I’ll give...

Since its inception in the early 2000s, compressive sensing has become a well-established paradigm for efficient signal recovery, with applications ranging from medical imaging to scientific computing. More recently, data-driven reconstruction...

For two multiplicatively independent positive integers p and q, Furstenberg (2019) conjectured that the transformations px mod 1 and qx mod1 are transverse. This means that the Hausdorff dimension of the intersection of two closed invariant sets is...

The Brauer–Manin obstruction provides a powerful framework for explaining failures of the Hasse principle for rational points on algebraic varieties. While many known examples arise from the algebraic part of the Brauer group, comparatively few...

I will survey the state of the art on the regularity theory for multiplicity 2 integral stationary currents. The talk will be based on joint work with C. De Lellis and J. Hirsch, and will touch upon recent work of Becker Kahn, Minter and...

The Haas Lab in the Centre for Brain Health at UBC designs and constructs ultrafast 3D-imaging two-photon microscopes, in vivo single-cell transfection strategies, and 4D post-imaging analytics to investigate the roles of sensory experience in the...
