Making a Splash, Breaking a Neck: The development of complexity in physical systems

The fundamental laws of physics are very simple. They can be written on the top half of an ordinary piece of paper. The world about us is very complex. Whole libraries hardly serve to describe it. Indeed, any living organism exhibits a degree of c   more››

The Good, the Bad, and the Awful: Scientific Simulation and Prediction

Worthwhile computer simulations are done to explore uncharted territory, resolve a well-posed scientific or technical question, or to make a design choice. Some excellent work is reviewed. Some less happy stories are recounted. I th   more››

Eigenvalue Problem and a New Product in Cohomology of Flag Varieties

This is a report on my joint work with P. Belkale. We define a new commutative and associative product in the cohomology of any flag variety G/P (which still satisfies the Poincaré duality) and use this product to generate certain inequalities wh   more››

Non-reductive group actions and symplectic implosion

Given a linear action of a complex reductive group on a projective variety X, geometric invariant theory provides us with an open subset of X (the set of stable points) which has a well-behaved quotient, and a compactification of this quotie   more››

Going with Flow and Updating Ocean Models

Much data in the ocean come from Lagrangian instruments that float or drift. Mathematical issues arise from the need to assimilate these and other data into ocean models.   more››

The sharp isoperimetric inequality on minimal submanifolds

We will describe the history of the conjecture that the isoperimetric inequality with the Rn constant should hold for a domain on a minimal submanifold of dimension n in Euclidean space. We will then describe a new method which pr   more››

Scheduling, Percolation, and the Worm Order

When can you schedule a multi-step process without having to take backward steps? Critical are an old concept called "submodularity", a new structure called the "worm order", and a variation of what physicists call "percol   more››

Recent developments on the well-posedness of dispersive equations

We will review the progress in the last 20 years on the well-posedness theory of dispersive equations, concentrating in the case of the Korteweg- de Vries equation to illustrate it. We will then describe some of the current challenges in the area,   more››

Quantum Mechanics, the Stability of Matter, and Quantum

Ordinary matter is held together with electromagnetic forces, and the dynamical laws governing the constituents (electrons and nuclei) are those of quantum mechanics. These laws, found in the beginning of last century, were able to account for the   more››

10th Anniversary Speaker Series 2007

The peculiar quantum-mechanical properties of the ground states of Bose gases that were predicted in the early days of quantum-mechanics have been verified experimentally relatively recently. The mathematical derivation of these properties from Sc   more››

A Phragmen-Lindelof and Saint Venant principle in harmonic analysis

Let S be a linear space of vector valued functions u(y) on the half-line whose values belong to some Banach space. We suppose that S is translation invariant; that is, if u(y) belongs to S, so does u(y+t) for all t>0. S is called 'interior comp   more››

Statistical modeling in setting air quality standards

The earth's atmosphere is a stochastic complex system which includes amongst other things pollution fields some of which derive from anthropogenic sources. Because of their negative health impacts, these fields are now the subject to regulation. H   more››

On Some of the Differences Between Z and Z^2 in Dynamics

Around 1970 it was discovered that measure preserving actions of Z^2 on probability spaces can have remarkably different properties from Z-actions, i.e. from actions of single transformations. Many of these differences can be described as 'rigidit   more››

Emergence and Flocking

We give a mathematical model with ordinary differential equations and the graph laplacian towards the problem: what decentralized mechanisms give rise to common features as language? A critical exponent plays a role in this deterministic setting.   more››

Topology, data and vision

Large data sets usually have some geometric core. We give some results toward understanding that core.   more››

Feature Selection through Lasso: model selection consistency and the BLasso algorithm

Information technology advances are making data collection possible in most if not all fields of science and engineering and beyond. Statistics as a scientific discipline is challenged and enriched by the new opportunities resulted from these high   more››
