Chaos & Complex Systems Seminar
A physics approach to understanding complex networks (Clay Memorial Lecture)
Time: 12:05 pm
Place: 4274 Chamberlin (refreshments will be served)
Speaker: Michelle Girvan, University of Maryland
Abstract: Many natural, technological, and social systems take the form of networks. Examples include metabolic networks, the Internet, and friendship networks. In the last decade or so, the new field of aEurooenetwork scienceaEuro has emerged, with physicists playing a key role applying methods from statistical mechanics and nonlinear dynamics to understand the behavior of these complex networks. In this talk, I will discuss how a physics approach to such problems can give us new insights into social, biological, and technological systems, and IaEuroTMll give several examples from my own research.<br>
This talk was made possible by a generous donation from Jane Clay in memory of her late husband Clarence Clay (1923-2011) who was an active participant in the seminars and who was a student of physics and professor in the Department of Geoscience specializing in oceanography at the University of Wisconsin.

Theory Seminar (High Energy/Cosmology)
The Many Ways to Galileon Inflation and an Intriguing Window in Parameter Space
Time: 4:00 pm
Place: 5280 Chamberlin
Speaker: Matteo Fasiello, Case Western Reserve University
Abstract: Galileon theories enjoy a number of properties that make their use in inflationary setups particularly compelling. We will illustrate how one arrives at a stable and predictive theory of Galileon inflation and characterize the predictions of this model. We further show how a region of the parameter space of the theory is consistent with a small bispectrum--large trispectrum configuration.
