Random matrix theorists of the mid-20th century noticed that the eigenvalues of certain Gaussian matrix ensembles act like a 'one-dimensional log-Coulomb gas'. This physical model has since become well-understood in the language of Boltzmann statistical mechanics. In this talk we introduce a nonarchimedean analogue, use a combinatorial method to establish basic results, and briefly discuss their physical interpretation. Time permitting, we'll also discuss how these results simplify in the special case that the gas particles are identical.

Mathematics Graduate Committee is inviting everyone to participate in an event during Graduate Appreciation week on Friday April 5 starting at 5:00pm in MSLC.

The event will feature (i) reception, (ii) research showcase of graduate students, and (iii) professional development activities specific to Mathematical Sciences.

We ask that you register and let us know of special topics of interest so we can plan; please use the link http://oregonstate.qualtrics.com/jfe/form/SV_ebAyE5WOSQq4tAp.

I will discuss recent results on the analysis of the vanishing viscosity limit, that is, whether solutions of the Navier-Stokes equations converge to solutions of the Euler equations, for incompressible fluids when walls are present. At small viscosity, a viscous boundary layer arise near the walls where large gradients of velocity and vorticity may form and propagate in the bulk (if the boundary layer separates).
