"Tropical Geometry and Real Algebraic Curves"

http://www.dm.unipi.it/~bertrand/Seminari.html


ABSTRACT : We will give the formal definition of tropical varieties and
explain how algebraic curves (and hypersurfaces) are related to tropical
ones. This talk will be based on articles of Mikhalkin ( [Mik00] and
[Mik]) and Shustin ([Shu]).

We will define the amoeba of an algebraic hypersurface and show how to get
the corresponding tropical hypersurface. We will also give the general
definition of a tropical variety and sketch the proof of 'Bezout' tropical
theorem.

If times allows, we'll give an application of amoebas in topology of real
algebraic curves.
