Topic:
Geodesics in First Passage Percolation
Date & Time:
Tuesday, December 6, 2016 - 14:00 to 15:00
Speaker:
Christopher Hoffman, University of Washington
Location:
Room 264, Geography Building, 3663 Zhongshan Road North, Shanghai
We will discuss recent results about the relationship between the limiting shape in first passage percolation and the structure of the infinite geodesics. We will present a solution to the midpoint problem of Benjamini, Kalai and Schramm. This is joint work with Gerandy Brito and Daniel Ahlberg.
