Discrete differential geometry: theory and applications. Sophisticated freeform structures made of glass and metal panels are omnipresent and their architectural design has been shown to be intimately related to a new area of mathematics, namely discrete differential geometry. This project is concerned with the theoretical basis of discrete differential geometry and its real world applications.
Symmetric functions and Hodge polynomials. This project aims to explain a connection between two seemingly disparate mathematical notions: mixed Hodge polynomials of certain varieties, naturally arising in algebraic geometry, and Macdonald polynomials from the theory of symmetric functions. This project will resolve this connection using symmetric function theory, algebraic combinatorics and representation theory.

This project aims to answer important geometric questions about subvarieties of the affine flag variety which are fundamental to algebraic geometry and number theory. It will answer basic questions about these central objects of mathematics, affine flags and their subspaces, using powerful new methods which combine ideas from geometry and algebra. The project expects to include finding the patterns of non-emptiness of these subvarieties and formulae for their dimension. It will develop and apply new methods which combine folded galleries and the geometry of Euclidean reflection groups, and these methods will have applications in algebraic combinatorics and representation theory. The project will also inspire productive connections between geometric group theory, a new and fast-growing area, and the classical fields of algebraic geometry, algebraic combinatorics and representation theory.Read moreRead less
Springer fibres, nilpotent cones and representation theory. This project will address new ideas and famous unsolved problems in the field of algebra known as representation theory, by studying the geometry of spaces called Springer fibres and nilpotent cones. This will keep Australian mathematics in the forefront of developments in this internationally active field, which is central to modern mathematics.

The project aims to leverage recent cutting-edge advances in the area of Teichmueller dynamics to answer longstanding open questions from algebraic geometry on the moduli space of curves, an object with deep connections to many diverse areas of science including quantum gravity and theoretical physics. The project expects to generate new theories and increased understanding in both areas through the innovation of relating these perspectives, as well as uncovering new connections between the viewpoints. Further benefits should include building international collaborations and the contribution of this diverse perspective to the growing algebraic geometry community in Australia and to mathematics and related scientific fields more generally.Read moreRead less

New Compactifications of Moduli Spaces of Curves. A moduli space is a geometric representation of a system of algebraic equations. Many fundamental problems in algebra, dynamics and physics can be reformulated as questions concerning the geometry of moduli spaces, in particular the moduli space of curves.

Many fundamental problems in algebra, dynamics and physics can be reformulated as questions concerning the geometry of moduli spaces, in particular the moduli space of curves. This project will produce a systematic classification of compactifications of the moduli space of curves, and develop new tools for investigating the geometry of these compactifications. One of these compactifications already lies at the centre of an extraordinary web of connections linking together topology, combinatorics and quantum field theory, and there is a strong possibility that this web fits into a more comprehensive picture involving all compactifications on an equal footing.Read moreRead less

One of the most spectacular recent advances in mathematics was Perelman's resolution of Thurston's geometrisation program for three-dimensional spaces. This makes it very important to understand sets of geometric structures on such spaces, called moduli spaces. The challenge of this project is to develop practical methods to compute moduli spaces, understand their global properties, and use them to define new invariants giving insights about shape, geometry and algebra of a space. This is a key problem as moduli spaces describe whether a space is rigid or can be deformed. They are a central object in several fields of mathematics, including geometry and topology, gauge theory, dynamical systems, mathematical physics and invariant theory.Read moreRead less
