New Directions in Derived Algebraic Geometry

Objective

New Directions in Derived Algebraic Geometry: In this proposal we propose to give a new impulsion on derived algebraic geometry by exploring new domains of applicability as well as developing new ideas and fundamental results. For this, we propose to focus on the, still very much unexplored, interactions of derived algebraic geometry with an extremely rich domain: singularity theory (to be understood in a broad sense, possibly in positive and mixed characteristics, but also singularities of meromorphic flat connections and of constructible sheaves). We plan to use the fruitful interactions between these two subjects in a two-fold manner: on the one hand derived techniques will be used in order to prove long standing open problems, and on the other hand we propose new developments in derived algebraic itself and thus open new research directions.The proposal has three major parts, interacting with each other in a coherent manner. In a first part we explore some direct applications of derived techniques to the study of singularities of degenerating families of proper schemes with the objective to prove a long standing major conjecture in the subject: the Bloch’s conductor formula. This is achieved by the introduction of a new trend of ideas in non-commutative geometry and more precisely by the introduction of a trace formula in the non-commutative setting. The second part is devoted to the exploration of trace and index formula for sheaves in two different, but very similar, setting: l-adic constructible sheaves and quasi-coherent sheaves with flat connections along a given algebraic foliations. In a third part we propose to make progress towards an unexplored domain: moduli spaces of flat, possibly irregular, connections on higher dimensional varieties and their relations with Poisson and symplectic geometry. The objective here is a far reaching generalization of fundamental results on moduli spaces of flat connections on open curves and their symplectic aspects.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
