We explore the location of the zeros and poles of the Pade approximations to the Riemann Zeta function. The patterns are striking and the computations difficult. Little is proved but much is suggested. This, of course, is intimate to the Riemann...

For Markov random fields temporal mixing, the time it takes for the Glauber dynamics to approach it's stationary distribution, is closely related to the spatial mixing properties of the measure such as uniqueness and the reconstruction problem. Such...

Microorganisms such as bacteria and spermatozoa move in a world where viscous forces completely dominate inertial forces, and the time evolution of their motion may be thought of as a sequence of steady-state snapshots. In this world, what motility...

The question is examined, as to whether a given rigid body will float or sink in a bath of liquid under the influence of surface tension, in a prescribed gravity field.

Time & Date: 12:00 p.m., Friday, November 28, 2008 Speaker: Weiyong He, PIMS Subject: ``Extremal metrics and the Calabi flow'' Location: WMAX 216 Abstract: In 1980s, Calabi introduced extremal metrics over K\"ahler manifolds as a generalization of...

We survey some recent results on Hessian, gradient estimates, regularity, and global rigidity for special Lagrangian equations with certain convexity. The gradient graph of the solutions are minimal Lagrangian submanifolds in Euclidean space. The...
