Tropical oriented matroids (and triangulations of products of simplices)

Student-Run Discrete Math Seminar

Speaker: Kristen Freeman, UC Davis
Location: 2112 MSB
Start time: Thu, Jan 21 2010, 12:10PM

I will briefly go over what tropical geometry is and then review the definition of tropical oriented matroids and triangulations of products of simplices. Then I will discuss how to walk around a triangulation and outline a proof that when $n=3$ there is a one to one correspondence between the triangulations of the product of simplices, $\Delta_{n-1} \times \Delta_{d-1}$, and tropical oriented matroids with parameters $(n,d)$.
