Title: Matrix iterative methods from the historical, analytic, application, and computational perspective
Abstract: Modern matrix iterative methods represented, in particular, by Krylov subspace methods, are fascinating mathematical objects that integrate many lines of thought and are linked with hard theoretical problems.
Krylov subspace methods can be seen as highly nonlinear model reduction that can be very efficient in some cases and not easy to handle in others. Convergence behaviour is well understood for the self-adjoint and normal [...]]]>http://depts.washington.edu/amath/zdenek-strakos-charles-university-prague/feed/0Barbara Keyfitz, Ohio State University

Title: Linear and Nonlinear Waves in Gas Dynamics
Abstract: This talk explores some puzzles of multidimensional conservation laws (quasilinear hyperbolic partial differential equations) by looking at two types of characteristic families in a model system: the Euler equations of compressible fluid flow. There is as yet no existence theory for such systems, and a considerable amount of recent activity raises questions of whether these equations, and others like them, are even well-posed. The
classical theory of characteristics provides a [...]]]>http://depts.washington.edu/amath/barbara-keyfitz-ohio-state-university/feed/0Drs. Ivana Bozic and Tim Leung join Amath faculty

Ivana is joining the department as an Assistant Professor. She is currently a postdoctoral fellow in the Department of Mathematics and a Research Scientist in the Program for Evolutionary Dynamics at Harvard.

Title: Complex oscillations: mixed modes and bursting in dynamical systems with multiple time scales
Abstract: Multiple time scales have a profound impact on dynamical systems. The generic behaviors found in this setting include bursting, chaotic relaxation oscillations and mixed mode oscillations. Recent advances in theory and accompanying computational methods have dramatically improved our understanding of these complex temporal behaviors. A natural classification of different types of bursting and mixed modes is developed and used as a foundation for computational [...]]]>http://depts.washington.edu/amath/john-guckenheimer-cornell/feed/0Emmanuel Candes, Stanford

Title: Beyond Compressed Sensing: The Effectiveness of Convex Programming in the Information and Physical Sciences
Abstract: This talk discusses three concrete problems characterized by incomplete information about an object of interest. The first is the century-old phase retrieval problem where intensity-only measurements – phase information is completely missing – are available about an image as in X-ray crystallography, and we wish to recover the phase. The second is the super-resolution problem where one can only observe the low-frequencies of [...]]]>http://depts.washington.edu/amath/emmanuel-candes-stanford/feed/0Anthony Patera, MIT

Title: PDE Apps for Education; Application to Heat Transfer, Elasticity, and Acoustics
Parametrized PDE (Partial Differential Equation) apps are PDE solvers which satisfy stringent per-query performance requirements: -second problem specification time; -second problem solution time, field and outputs; solution error, specified metrics; -second solution visualization time. Parametrized PDE apps are particularly relevant in many-query, real-time, and interactive contexts such as design, parameter estimation, monitoring, and education.
In this talk we describe and demonstrate our PDE app methodology. The numerical approach [...]]]>http://depts.washington.edu/amath/anthony-patera-mit/feed/0Andrea Bertozzi, UCLA

Title: Mathematics of Crime
Abstract: There is an extensive applied mathematics literature developed for problems in the biological and physical sciences. Our understanding of social science problems from a mathematical standpoint is less developed, but also presents some very interesting problems, especially for young researchers. This lecture uses crime as a case study for using applied mathematical techniques in a social science application and covers a variety of mathematical methods that are applicable to such problems. We will review [...]]]>http://depts.washington.edu/amath/andrea-bertozzi-ucla/feed/0Terry Rockafellar, UW

Title: Multifidelity modeling: Risk and Reliability in Stochastic Optimization
Abstract: Problems of optimization are concerned with making decisions “optimally” however in many situations in management, finance and engineering, decisions have to be made without knowing fully how they will play out in the future. When the future is modeled probabilistically, this leads to stochastic optimization, yet the formulation of objectives and constraints can be far from obvious. A future cost or hazard variable may be a random variable which a [...]]]>http://depts.washington.edu/amath/terry-rockafellar/feed/0Swartz Center in Theoretical Neuroscience established at University of Washington; Shea-Brown and Fairhall will co-direct

Title: The “Hole Story”: how to solve problems in multiply connected domains
Abstract: Motivated by problems arising in the applied sciences, this talk surveys a new theoretical approach to solving problems in multiply connected planar domains as developed by the speaker (and his group) in recent years. Multiply connected domains are “regions with holes” and are ubiquitous in applications; whenever two or more objects/entities interact in some ambient medium the analysis may call for the methods discussed in this [...]]]>http://depts.washington.edu/amath/darren-crowdy/feed/0
