The study of algebraic varieties and their properties is vast and heterogeneous: one approach is the one given by motives (both Grothendieck’s and Deligne’s, but also by Voevodsky, Morel and Nori) and by the study of the arithmetic properties through Hodge theory, Shimura varieties, as well as L-functions and Iwasawa’s theory.

Specific subjects are

- p-adic Hodge theory, Shimura varieties and Torelli locus, Deligne 1-motives (Fabrizio Andreatta).

- Motives (a la Grothendieck, Deligne, Voevodsky, Nori, etc.) versus homotopical algebra and Hodge theory (Luca Barbieri-Viale).

- Elliptic curves, modular forms, L-functions, Iwasawa theory, higher dimensional cycles (Massimo Bertolini).

- Motives (after Grothendieck, Voevodsky, Morel, etc.), finiteness notions and Bloch’s conjecture on surfaces, K-theory (Carlo Mazza).

-  Selberg's class and automorphic functions, transcendence problems, and exponential sums (Giuseppe Molteni).

- Arithmetic of abelian varieties, p-adic L-functions, Heegner points and Stark-Heegner points (Marco Seveso).
