Upcoming Events

September 2018

Bojko Bakalov, NC State, An operadic approach to vertex algebras and Poisson vertex algebras

September 24 | 3:00 pm - 4:00 pm EDT

Following Beilinson and Drinfeld, we describe vertex algebras as Lie algebras in a certain pseudo-tensor category. More precisely, starting from a vector superspace V with a linear operator on it, we introduce the operad of n-ary chiral operations on V. When V is…

Susan Minkoff, UT Dallas, Microseismic Source Estimation via Seismic Inversion

September 25 | 3:00 pm - 4:00 pm EDT

Accurate estimation of microseismic events (small earthquakes) generated during hydraulic fracturing of low permeability rocks such as shale enables important characterization of hydraulic fracture networks. Determining the orientation of the fracture is important in characterizing the effectiveness of the stimulation…

Michael Strayer, University of North Carolina at Chapel Hill, Finite and infinite minuscule and d-complete posets from Kac-Moody representations

October 1 | 3:00 pm - 4:00 pm EDT

The finite minuscule and d-complete posets generalize Young and shifted Young diagrams.  They have many nice combinatorial properties; for example, minuscule posets are Gaussian and Sperner, and d-complete posets have the hook length and jeu de taquin properties.  Infinite analogs…

Vladimir Druskin, Worcester Polytechnic Institute, Reduced Order Models, Networks and Applications to Modeling and Imaging with Waves

October 2 | 3:00 pm - 4:00 pm EDT

Geophysical seismic exploration, as well as radar and sonar imaging, require the solution of large scale forward and inverse problems for hyperbolic systems of equations. In this talk, I will show how model order reduction can be used to address…

Min Hoon Kim, Korea Institute for Advanced Study, A family of freely sliced good boundary links

October 16 | 4:45 pm - 5:45 pm EDT

The still open topological surgery conjecture for 4-manifolds is equivalent to the statement that all good boundary links are freely slice. In this talk, I will show that every good boundary link with a pair of derivative links on a…
