Nonsmooth, Nonconvex Optimization

There are many algorithms for minimization when the objective function is differentiable or convex, but few options when it is neither. We describe two simple algorithmic approaches for minimization of nonsmooth, nonconvex objectives: BFGS (a new more››

Design of a high quality optical resonator

We consider resonance phenomena for the scalar wave in an inhomogeneous medium. Resonance can be described as a solution to the wave equation that is spatially localized while its time dependence is (mostly) harmonic except for decay due to radiat more››

Gradient Flows and Energy Landscapes II

Micromagnetics deals with the spatial pattern formed by the magnetization of a ferromagnet. From the point view of mathematics, micromagnetics is an ideal testbed for a pattern-forming system in materials science: There are abundant experiments on more››

Structure Theorems in Graph Theory

Fix a graph H. What is the most general graph that does not contain H? In other words, how do we explicitly construct all the graphs that do not contain H? To begin to make this precise, we have to say what 'contain' means;; we have more››

A unified approach to modelling trajectories

The talk will concern the employment of stochastic gradient systems in the modeling and statistical analysis of biological and ecological processes of moving particles. The work is stimulated by scientific questions and data sets of the movements more››

Data Stream Processing with Resource Adaptive Computation

The problem of streaming data has gained importance in recent years because of advances in hardware technology. The ubiquitous presence of data streams in a number of practical domains has generated a lot of research in this area. Example applicat more››
