Geometric methods in quantum theory. Quantum theory is the fundamental language of physics, it describes the small scale structure of matter and possibly space-time. The advent of sophisticated models, particularly of quarks has emphasised geometric structure as a basic component of the theory. The issues thrown up by quantum theory are similar to problems encountered in the geometry of manifolds so that tools from the latter have been successfully employed in the former and vice-versa. ....Geometric methods in quantum theory. Quantum theory is the fundamental language of physics, it describes the small scale structure of matter and possibly space-time. The advent of sophisticated models, particularly of quarks has emphasised geometric structure as a basic component of the theory. The issues thrown up by quantum theory are similar to problems encountered in the geometry of manifolds so that tools from the latter have been successfully employed in the former and vice-versa. Previous work of the Chief Investigators has shown the importance of geometric structures known as gerbes which this Project will extend and apply in novel ways.Read moreRead less

This project aims to approach several important problems in global differential geometry, by inventing new processes to deform geometric objects to simpler ones. The deformations are described by carefully constructed geometric evolution equations, designed to exhibit behaviour suited to the given problem. The project proposes methods for building such equations, and new techniques for their analysis. The research is expected to yield significant new results, both in differential geometry and in nonlinear heat equations, and should provide substantial progress towards resolving several important long-standing conjectures.

Triangulated categories and their applications. This project is at the cutting edge of modern, international research in mathematics. Having work of this calibre done in Australia raises our international prestige, and makes Australia a more attractive place for top-notch hi-tech companies. Furthermore, training our young people to such a high standard will have the long-term effect of raising our profile.
Energy, Cosmic Censorship and Black Hole Stability. Human progress is achieved by confronting fundamental questions, at the leading edge of knowledge. This project will lead to better understanding of space-time physics, and of the properties of singular solutions of non-linear hyperbolic equations. Such equations govern a wide range of physical phenomena, including fluid flow, weather and electromagnetic fields.
Nonlinear Partial Differential Equations: Singularities, Potential Theory, and Geometric Applications. The main objective of the project is to study properties of solutions to fully nonlinear, elliptic partial differential equations. Rather than studying more traditional existence-uniqueness problems the main task will be to investigate qualitative questions. These concern the behaviour of solutions to the equations, the description of possible pathologies and singularities the solutions can hav ....Nonlinear Partial Differential Equations: Singularities, Potential Theory, and Geometric Applications. The main objective of the project is to study properties of solutions to fully nonlinear, elliptic partial differential equations. Rather than studying more traditional existence-uniqueness problems the main task will be to investigate qualitative questions. These concern the behaviour of solutions to the equations, the description of possible pathologies and singularities the solutions can have, and conditions for the absence of singularities. Understanding of the singular behaviour of solutions is very important for applications in geometry, physics, elasticity, and mechanics. From this point of view, probably the most important problem is to find explicit information about singularities of solutions.Read moreRead less
Derived categories and their applications, especially in K-theory, topology and algebraic geometry. Algebraic geometry, topology and algebraic K-theory are mathematical disciplines that study different aspects of geometry. In all these areas of study, derived categories have proved to be powerful tools. This project aims to use derived categories to advance our understanding of geometry. Involved are some of the main open questions in geometry from the second half of the twentieth century.

The research is being nominated for the Complex/Intelligent Systems Priority Area. Geometry is relevant in two ways. Secure and/or error correcting codes are often based on algebraic geometry. And modelling concurrency problems involves homotopy theory.Read moreRead less
