摘 要

Tropical geometry is a newly developed branch of mathematics, it has connections with symplectic geometry, combinatorics, computational commutative algebra, algebraic geometry and so on. I will discuss one application in algebraic geometry, which is the so-called tropical compactification. This gives a nice way to compactify subvarieties of tori. In some special cases, one can even obtain a log canonical compactification in the sense of minimal model program. Examples include moduli space of n-poined stable curves of genus 0, moduli space of del Pezzo surfaces of degree 6,7, and moduli space of 6 points configuration in projective plane in linear general position.
