Abstract: Tropical geometry has been developed for several decades, where the adjective 'tropical' was coined by French mathematicians in honor of the Hungarian-born Brazilian computer scientist Imre Simon. Intuitively, when you want to solve polynomial equations over a valued field (e.g. p-adic numbers), the corresponding geometric picture (i.e. tropical variety) tells you how your solution should look like. In this talk, we will deal with the simplest case – curves, and see that it enjoys some properties coming from classical algebraic geometry.
