Algebraic stacks are a geometric manifestation of algebraic and physical phenomena. Stacks provide a fundamental mathematical structure to study questions in geometry, topology and number theory having deep applications to string theory and complexity theory. This project will prove new fundamental theorems about algebraic stacks that will have broad implications. In particular, the new results obtained on algebraic stacks will be applied in order to resolve a long-standing open problem in algebraic geometry. Specifically, the project will provide a new description of the birational geometry of one of the most interesting and studied algebraic varieties, the moduli space of smooth curves.Read moreRead less

Summary
Algebraic stacks through the Tannakian perspective. Algebraic stacks are natural types of spaces to consider when parameterising geometric objects in mathematics and physics. The Tannakian formalism allows one to view algebraic stacks through the way it acts on other geometric objects. This project aims to employ the perspective provided by the Tannakian formalism to prove innovative and foundational results in order to elucidate the geometry of algebraic stacks.
Towards a new concrete theory of cohomology: a fundamental concept in geometry. This project will develop a geometric linearisation method related to Witt vectors, an exotic but important number system. This will let us take one more step towards solving a fifty-year-old mystery: to find the elusive universal linearisation in algebraic geometry, which is the linearisation that controls all the others.

Derived categories and their many applications. This project aims to work on major open problems in algebra, towards the solution of conjectures that have been around for decades. The proposed research is ground-breaking, introducing new methods to problems that have stumped experts around the world. The planned techniques the project will use come from homological algebra, more specifically, from derived categories. Preliminary work, using the new methods, has already led to major advances on w ....Derived categories and their many applications. This project aims to work on major open problems in algebra, towards the solution of conjectures that have been around for decades. The proposed research is ground-breaking, introducing new methods to problems that have stumped experts around the world. The planned techniques the project will use come from homological algebra, more specifically, from derived categories. Preliminary work, using the new methods, has already led to major advances on what was previously known. The project is ambitious: if really successful, it is hoped to reshape the subject and deepen our understanding of the field, but even more modest achievements are expected to clarify and improve on work by international experts over four decades.Read moreRead less
Witt vectors and their applications in arithmetic algebraic geometry. This project aims to continue the development of arithmetic algebraic geometry. This is the field of fundamental mathematics that forms the basis for much of cryptography and coding theory, which are the fields of applied mathematics that allow for secure and efficient electronic communication.

This project aims to continue the development of arithmetic algebraic geometry. This is the field of fundamental mathematics that forms the basis for much of cryptography and coding theory, which are the fields of applied mathematics that allow for secure and efficient electronic communication. The approach will be to apply recent advances in the theory of global Witt vectors to resolve some open questions involving numerical properties of polynomial equations. This is expected to lead to advances in a field which is of fundamental importance in mathematics generally and which is also the basis of secure internet communication.Read moreRead less
