Title: Tropical Geometry and Applications

Abstract: Tropical geometry is the geometry over the max-plus algebra.  It is a degeneration or a limit of classical geometric objects under the logarithm or valuation map. We will discuss how to tropicalize algebraic sets, semialgebraic sets, and convex sets, and highlight some applications to truncated moment problems and matrix completion problems in applied algebra and geometry.
