Equiangular lines are collections of lines in Euclidean space, all passing through the origin and forming the same angle with one another. Given a fixed angle, a fundamental question is: what is the maximum number of such lines? I will present a...

Although we often introduce group theory to students using groups of symmetries, we tend to move quickly away from these intuitive representations into the realm of axioms and deductions. There are plenty of good reasons for this, not least of which...

We are extremely pleased to announce that Dr. Inwon Kim, Professor of Mathematics at UCLA, will deliver an upcoming lecture in the Hugh C. Morris Lecture Series. Dr. Kim is internationally recognized for her influential work in analysis and PDEs...

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...

A number is called a "period" if it can be expressed as the volume of a region in Euclidean space, defined by polynomial inequalities with rational coefficients. Many famous constants, such as π, log(2) and special values of the Riemann zeta function...

Secure online communications and financial transactions depend on public key cryptography—but the methods we use today are susceptible to attack by quantum computers. When that will happen is uncertain, though estimates range from 5 to 25 years. This...

The Niven Lecture is an annual lecture given to graduating math students, their family members and the general public at UBC. Between 1905 and 1910 the idea of the random walk, now a major topic in applied math, was invented simultaneously and...

Led by our Education Coordinator, Jane Butterfield, and a team of enthusiastic volunteers, we'll be offering visitors a fun and interactive glimpse into the Math Mania program we normally bring to local elementary schools. Join us and experience the...

Lagrangian submanifolds are a central object of study in symplectic topology. Their rigidity properties have been uncovered via Floer theory since the early ’90’s. The talk will briefly review the subject, in particular how triangulated category...

Christos Thrampoulidis, the 2024 PIMS/UBC Early Career Award Winner, will present a talk. Abstract Deep learning models are often seen as black boxes, their complexity stemming from integrating numerous architectural components across multiple layers...
