We will look at the history of The Theory of Branched Minimal Immersions from Jesse Douglas' solution of the Plateau Problem in 1931 ( for which he, along with Lars Ahlfors, received the first Fields Medals in 1936) to the present. We will propose a new way of looking at the theory which is, from the outset, global rather than local in nature.

In a celebrated paper, Dyson shows that the spectrum of a random Hermitian matrix, diffusing according to an Ornstein-Uhlenbeck process, evolves as non-colliding Brownian motions held together by a drift term. The universal edge, bulk and gap scalings for Hermitian random matrices, applied to the Dyson process, lead to novel stochastic processes,...

I will describe some recent progress on the regularity theory
for minimal hypersurfaces. Assuming stability of the hypersurfaces, the results to be presented establish a rather complete local regularity theory that is applicable near points of volume density less than 3. I will also present an existence result. The latter is joint work with
Leon...

The notion of Extremal K\"ahler metric generalizes both K\"ahler-Einstein
metric and K\"ahler metric with constant scalar curvature. Such metric on
the blow up of $\mathbb{C}P^n$ in a point was constructed explicitly by
Calabi. In this talk, we shall give a different construction of Calabi's
metric using Guillemin-Abreu theory on K\"ahler toric...

Calibrated submanifolds constitute special classes of minimal
submanifolds. Some of the most interesting types of calibrated
submanifolds arise inside of manifolds with special holonomy. Integrable
systems have been found lurking inside of these special calibrated
geometries. Beginning with the work of Haskins and Joyce on special
Lagrangian...

Let $M$ be a compact manifold of dimension $n \geq 3$. Along the > Yamabe flow, a Riemannian metric on $M$ is deformed according to the > equation $\frac{\partial g}{\partial t} = -(R_g - r_g) \, g$, where $R_g$ > is the scalar curvature associated with the metric $g$ and $r_g$ denotes > the mean value of $R_g$. > > It is known...
