Resolving central questions in the arithmetic of the Langlands programme
The Langlands programme is an effective tool for understanding the conjectural relationships between Galois representations and automorphic forms. While significant advances have been made in understanding Langlands structures, many questions remain unresolved owing to a limited grasp of Galois deformation theory in extreme degenerate situations. The ERC-funded MARARA project aims to tackle key questions in the arithmetic of the Langlands programme by integrating new robust and flexible methods into the study of Galois representations. Taking a multidimensional approach, it aims to gain insight into unresolved questions and demonstrate new instances of significant conjectures in arithmetic geometry and the theory of automorphic forms, such as the Fontaine-Mazur, the Serre’s and the Langlands functoriality conjectures.
Objective
Many of the most important questions in number theory and arithmetic geometry can be approached through the theory of Galois representations. A powerful tool to understand such representations is the Langlands programme, which describes the conjectural relations between Galois representations and automorphic forms. Landmark results in this direction include the proof of the modularity conjecture for (the Galois representations associated to) elliptic curves over the field of rational numbers and the proof of Serre's conjecture.
Dramatic advances in our understanding of the structures of the Langlands programme in the last 20 years have made it possible to extend the scope of these theorems, both to more general classes of Galois representations and to more general base number fields. However, the most general and conclusive statements remain out of reach, in large part due to our poor understanding of Galois deformation theory in the most degenerate situations.
The goal of this proposal will be to address central questions in the arithmetic of the Langlands programme by introducing new techniques into the study of Galois representations that are robust, powerful, and flexible. We will take a multi-faceted and cohesive approach that will lead to a greater understanding of fundamental open questions, and the proofs of new cases of important conjectures, in arithmetic geometry and the theory of automorphic forms, including the Fontaine--Mazur conjecture, the general form of Serre's conjecture, and the Langlands functoriality conjectures.
