Ramanujan is dead. Long live Ramanujan

September 15, 2026 - 11:00 am to 12:00 pm

MATH 126

This talk is about Arthur packets and the Ramanujan-Petersson Conjecture. We will look at how recent progress on local Arthur packets leads to improved control on the non-temperedness of local components of automorphic representations. Read more

Log-Concavity and Log-Convexity via Distributive Lattices

September 15, 2026 - 4:00 pm to 5:00 pm

ESB 4133

The FKG inequality is a powerful tool for proving inequalities in distributive lattices. We show how a special case, which we call the Order Ideal Lemma, can be used to demonstrate a wide array of log-concavity and log-convexity results in a combinatorial manner. We use the ... Read more

Some curves don’t arise

September 16, 2026 - 3:00 pm to 4:00 pm

Math 204

Recent joint work with Artem Kotelskiy and Claudius Zibrowius gives a proof that the reduced version of Khovanov homology is insensitive to Conway mutation of knots over any coefficient field. In order to get our hands on this fact, we studied the relative version of Khovanov' ... Read more

Wind-wave breaking

September 18, 2026 - 3:00 pm to 4:00 pm

ESB 2012 and Zoom

Ocean waves forced by wind grow and eventually break, playing an important role in the coupling between the atmosphere and the ocean. Wave breaking modulates momentum and energy fluxes, controlling upper ocean currents affecting gas transfer and pollutant dispersion while air ... Read more

The Study of Wave Turbulence: A Meeting Ground for Mathematical Techniques (PIMS network-wide colloquium)

September 24, 2026 - 1:30 pm

Zoom - register here: https://ubc.zoom.us/meeting/register/iZvmEZ0IQEixMor4RQ0oWQ#/registration

Wave turbulence theory is a rich and expansive field, aiming to provide a framework for understanding how waves interact across different settings. Wave interactions occur over a wide range of scales and media—spanning from gravitational waves in the cosmos to ripples on the ... Read more
