Algebra/Topology Seminar, Bulent Tosun, University of Alabama
228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle : Contact geometry in low dimensions Abstract: This series of talks will be about explaining some fundamental open problems in three-dimensional contact geometry. This third talk will be on overtwisted vs. tight dichotomy (or flexible vs. rigid), and existence problem of tight contact structures.
