TITLE:    Tropical geometry

ABSTRACT: Starting form the definitions given in the previous talk, I 
will give a more formal definition of tropical variety (both in affine 
and projective case). Moreover I will introduce the tropical version of 
objects and invariants, known in the usal geometry: multiple points, 
intersection number, genus, degree.
