Let $P(s,A)$ be a transition probability on a general measurable space $(\S,\Sigma)$ with invariant probability $m$, and let $\Omega_1 =\S^{\mathbb N}$ be the space of trajectories with $\sigma$-field $\B_1 = \Sigma^{\otimes \mathbb N}$, with...

Compressed sensing theory explains why Lasso programs recover structured high-dimensional signals with minimax order-optimal error. Yet, the optimal choice of the program’s governing parameter is often unknown in practice. It is still unclear how...

Recent advances in single-cell gene sequencing data and high-dimensional data analysis techniques are bringing in new opportunities in modeling biological systems. In this talk, I discuss different approaches to develop mathematical models from...

Einsteins theory of General Relativity (GR) works remarkably well on Earth and inside our Solar System. However, there remain significant gaps in our understanding of gravity. One is the long- standing quest for a quantum theory of gravity. The other...

Indirect reciprocity explores how humans act when their reputation is at stake. The corresponding models describe how reputations change over time, depending on the actions people take, and on the social norms they employ. The first part of the talk...

To understand the fluid dynamics of marine phenomena fluid-structure interaction problems must be solved. Challenges exist in developing analytical and numerical techniques to solve these complex flow problems with boundary conditions at fluid...

Tensor decomposition has many applications. However, it is often a hard problem. In this talk I will discuss a family of tensors, called orthogonally decomposable tensors, which retain some of the properties of matrices that general tensors don't. A...

A video of this event is available on mathtube.org. Statistical science has a 200-year history of advances in theory and application. Data science is a relatively newly defined area of enquiry deriving from big data. The interplay between them, and...

A video of this event is available on mathtube.org. In this talk, I will give a survey of recent work I have done—some published, some unpublished—on the historical, mathematical, and philosophical problems related to the assignment of "sizes" to...

A video of this event is available on mathtube.org Anaerobic digestion is a complex, naturally occurring process during which organic matter is broken down into biogas and various byproducts in an oxygen-free environment. It is used for...
