Combinatorics Date:  Friday, February 03, 2012 Location:  3866 East Hall (4:10 PM to 5:00 PM) Title:  Triangulations of product of simplices Abstract:   After the work of Develin and Sturmfels on tropical convexity, Ardila and Develin defined tropical oriented matroids, and showed that they encode subdivisions of product of simplices. In a joint work with Yoo, we show that every triangulation of product of simplices encode a tropical oriented matroid. In this talk, I will give a survey on this topic, and introduce an ongoing project, on connections to matching fields studied by Bernstein and Zelevinsky.
