The aim of the workshop was to bring together the many researchers with interests in Unlikely intersections (algebraic groups, abelian varieties, Shimura varieties, Zilber-Pink, André-Oort, Manin-Mumford, Mordell-Lang…), Diophantine geometry (rational points, bounded height, Chabauty-Kim…), and the many related fields (o-minimality, functional transcendence, differential algebraic geometry, equidistribution, arithmetic dynamics, Galois representations…).
