Many modern data science tasks can be expressed as optimizing a complex, random function in high dimensions. The go-to method for such problems is Stochastic gradient descent (SGD), which performs remarkably well—c.f. the success of modern neural...

Any construction of a quantum computer requires finding a good set of universal quantum logic gates: abstractly, a finite set of matrices in U(2^n) such that short products of them can efficiently approximate arbitrary unitary transformations. The 2...

Combinatorial Configurations lay between block designs and hypergraphs. When these incidence structures can be embedded in the plane, we call them Geometric Configurations. In this talk, we will explore several results in the study of configurations...

Join us for an engaging presentation on "Unraveling the Mathematics of Single-Cell Dynamics" with Dr. Anotida Madzvamuse. This event is part of the UBC Applied Science Black Excellence in STEM (BEST) Speaker Series, in collaboration with the...

The generalized degree polynomial (GDP) of a tree is an invariant introduced by Crew that enumerates subsets of vertices by size and number of internal and boundary edges. Aliste-Prieto et al. proved that the chromatic symmetric function of a tree...

Individual and collective cell polarity has fascinated mathematical modelers for a long time. Recently, a more subtle type of symmetry breaking started to attract attention of experimentalists and theorists alike - emergence of chirality in single...

The Deligne-Mumford compactification, M 0 , n ⎯ ⎯ ⎯ ⎯ ⎯ ⎯ ⎯ ⎯ ⎯ ⎯ ⎯ , of the moduli space of n distinct ordered points on ℙ 1 , has many well understood geometric and topological properties. For example, it is a smooth projective variety over its...

Even though Euler products of L-functions are generally valid only to the right of the critical strip, there is a strong sense in which they should persist even inside the critical strip. Indeed, the behaviour of Euler products inside the critical...

In this talk, we consider reaction-diffusion and patch epidemic models with mass action or standard incidence mechanism and study the impact of limiting population movement on disease transmissions. We set either the dispersal rate of the susceptible...
