Election dynamics are a rich complex system, and forecasting next month's U.S. elections is an exciting, high-stakes problem with many sources of subjectivity and uncertainty. In this talk, we take a dynamical-systems perspective on election...

The distinguishing number of a graph is the smallest number of colors necessary to color the vertices so that no nontrivial automorphism preserves the color classes. If a graph can be distinguished with two colors, the distinguishing cost is the...

The PIMS-UBC Math Job Forum is an annual Forum to help graduate students and postdoctoral fellows in Mathematics and related areas with their job searches. The session is divided in two parts: short presentations from our panel followed by a...

Which real numbers arise as the entropies of continuous, multimodal, postcritically finite self-maps of real intervals? This is the "one-dimensional" analogue of a more famous open question: which real numbers arise as the dilatations of pseudo...

Motivated by neuroscience phenomena, the study of convex neural codes seeks to characterize how convex sets may intersect and overlap one another in Euclidean space. We will see how certain arrangements of convex sets, called "sunflowers" and...

Nature has evolved many mechanisms for achieving directed motion on the subcellular level. The burnt-bridges ratchet (BBR) is one mechanism used to achieve superdiffusive molecular motion over long distances through the successive cleavage of surface...

As the underlying configuration behind many elegant finite structures, partial difference sets have been intensively studied in design theory, finite geometry, coding theory, and graph theory. Over the past three decades, there have been numerous...

We formulate, using heuristic reasoning, precise conjectures for the range of the number of primes in intervals of length yy around xx, where y≪(logx)^2y≪(log⁡x)^2. In particular, we conjecture that the maximum grows surprisingly slowly as yy ranges...

The first speaker will be Dr. William Witczak-Krempa of the Université de Montréal. His talk will be "Conformal field theories & quantum phase transitions: an entanglement perspective". The talk is intended for both mathematics and physics audiences...

The Number theory and combinatorics seminar is starting up again today at noon. There will be an organizational meeting and problem session. If you would like to attend the registration link is here. Register in advance for this meeting. After...
