AbstractEarthquakes are natural generalisations of Fenchel-Nielsen twists deformations on Teichmueller space, and Thurston’s remarkable earthquake theorem asserts that any hyperbolic metric on a given closed surface can be deformed to any other by a unique (left) earthquake. This was famously employed by Kerckhoff in his proof of the Nielsen realisation problem, which quickly cemented their im...
Abstract:We will survey aspects of algebraically defined link homology theories and discuss several key open questions that come out of these structures.SpeakerMikhail Khovanov is a recognized leader of the “categorification” program, which plays an important role in modern mathematics and physics.Khovanov earned his Ph.D. in 1997 under the supervision of Professor Igor Frenkel at Yale Unive...
