*Isac Hedén - Uppsala University*

It was shown by Makar-Limanov himself that the Makar-Limanov invariant of Russell's hypersurface X is nontrivial and thus that X is only diffeomorphic, but not isomorphic to affine 3-space. Russell's...

*Peter Sarnak, the 2011 Mahler Lecturer - Princeton University, USA*

The correspondence principle in quantum mechanics is concerned with the relation between a mechanical system and its quantization. When the mechanical system are relatively orderly ("integrable...

*Marston Conder - University of Auckland*

Symmetry is pervasive in both nature and human culture. The notion of chirality (or ‘handedness’) is similarly pervasive, but less well understood.In this lecture I will talk about a number of...

*Prof. B. S. Goh - Institute of Mathematical Sciences, University of Malaya, Malaysia*

Current numerical methods, like the trust region method in solving optimization problems with equality constraints, use a quadratic model to construct an iteration. This is motivated by the Newton...

*Peter Sarnak, the 2011 Mahler Lecturer - Princeton University/IAS*

One of the consequences of the recent proof by Holowinski and Soundararajan of the holomorphic "Quantum Unique Ergodicity Conjecture" is that the zeros of a classical holomorphic hecke cusp forms...

*Andrew Tremayne - UNSW and University of Liverpool*

Time series models for count data are an active area of research. The integer status of data is often preserved using a device such as the binomial thinning operator in place of multiplication as in...

*Dr Christopher Angstmann - School of Mathematics and Statistics*

The Mathematical and Statistical Biology Symposium is an informal forum for researchers to hear about work in progress. The format consists of a 30 minute presentation followed by coffee and cake in...

*Peter Donovan - UNSW*

The note by Claude Schochet with this title in Notices of the AMS August 2009 refers back to the Donovan-Karoubi work on twisted K-theory of 1969. The DK paper seems to have become something of a...

*Alexandra Gillett - UNSW*

Kaggle is a hosting platform for data modelling and prediction competitions. Governments, companies and researchers submit datasets and problems, then data scientists compete to produce to the best...

*Patricia Menendez - Public University of Navarre (Spain) and Swiss Federal Institute for Forest, Snow and Landscape Research WSL (Switzerland)*

Long-term records such as fossil pollen and stable oxygen isotopes reveal major fluctuations in the past environmental conditions, including abrupt climate changes and long term temperature shifts....
