Junior Seminar
Nell'ambito dei Junior Seminars, Martedì 12 dicembre 2023 alle ore 10:00, Luca Ferrigno (dottorando dell' Università degli Studi Roma Tre) terrà il seminario dal titolo "Unlikely Intersections in diophantine geometry".

Abstract:
We talk about "unlikely intersections" whenever we have a non-empty intersection between algebraic varieties that, for dimensional reasons, we do not expect to intersect: for example, if X, Y are varieties of dimensions r and s in a space of dimension n > r + s, we usually expect XY to be empty.
This expectation is the basis of many problems in diophantine geometry, which usually study the finiteness of the number of points satisfying some arithmetical conditions on algebraic varieties.
After an overview of some problems of unlikely intersections in algebraic tori, we will focus on unlikely intersections in families of elliptic curves.

Il seminario si svolgerà in presenza presso il Dipartimento di Matematica e Fisica, 
via della Vasca Navale, 84- aula B
