CARMA Special Semester

Special Semester on Mathematical Thinking

Monday, 5th Nov 2018 — Friday, 31st May 2019


The next CARMA special semester programme is on the theme of Mathematical Thinking, examining the conceptual and neurological basis of mathematical thought and creativity, different aspects of which are associated with brain structures evolved for different purposes. It will explore links to machine learning, which plays a critical role as a model for cognition, as well as cognitive psychology, neuroscience, philosophy and pure and applied mathematics, through a series of workshops and other events. Please visit the semester's webpage for details. Events will also be listed on the events page of the CARMA website.

CARMA and AMSI Workshop

AMSI-CARMA Workshop on Mathematical Thinking

Wednesday, 14th Nov 2018 — Friday, 16th Nov 2018

X803, NewSpace (City Campus)

Mathematics underpins much of the scientific and technological progress of modernity. This workshop will bring together experts to study the conceptual and neurological basis of mathematical thought and creativity, different aspects of which are associated with brain structures evolved for different purposes. We will explore links to machine learning, which plays a critical role as a model for cognition, as well as cognitive psychology, neuroscience, philosophy and pure and applied mathematics. For further information, please visit the workshop website. The conference is part of CARMA's Special Semester on Mathematical Thinking.

At this workshop, we will target discussions at forming new interdisciplinary collaborations and formulating concrete research questions with a view towards major grant applications in the ARC Discovery and linkage programmes, among others. Expected benefits arising from such collaborations include machine learning improvements, computer assistance for mathematical research and other high-level cognitive tasks, and improved insight into mathematics education at all levels.

Zero-Dimensional Symmetry Seminar

2:00 pm

Tuesday, 20th Nov 2018

(Location to be decided)

Dr Thibaut Dumont

(University of Jyväskylä)

Cocycles on trees and piecewise translation action on locally compact groups

In the first part of this seminar, I will present some geometric cocycles associated to trees and ways to compute their norms. Similar construction exists for Euclidean buildings but no satisfactory estimates of the norm is currently known. In the second part, I will discuss some ongoing research with Thibaut Pillon on actions the infinite cyclic group by piecewise translations on locally compact group. Piecewise translation actions have been well studied for finitely generated groups, e.g. by Whyte, and provide positive answers to the von-Neumann-Day problem or the Burnside problem. The generalization to LC-groups was introduced by Schneider. The topic seems to have interesting implications for tdlc-groups

Hausdorff dimension and normal subgroups of free-like pro-p groups

Hausdorff dimension has become a standard tool to measure the "size" of fractals in real space. However, it can be defined on any metric space and therefore can be used to measure the "size" of subgroups of, say, pro-p groups (with respect to a chosen metric). This line of investigation was started 20 years ago by Barnea and Shalev, who showed that p-adic analytic groups do not have any "fractal" subgroups, and asked whether this characterises them among finitely generated pro-p groups. I will explain what all of this means and report on joint work with Oihana Garaialde and Benjamin Klopsch in which, while trying to solve this problem, we ended up showing an analogue of a theorem of Schreier in the context of pro-p groups of positive rank gradient: any finitely generated infinite normal subgroup of a pro-p group of positive rank gradient is of finite index. I will also explain what "positive rank gradient" means, and why pro-p groups with such a property are "free-like".

Public Lecture

6:00 pm

Thursday, 29th Nov 2018

(Location to be decided)

A public lecture held as part of the CTAC 2018 conference on computational mathematics.


Prof. Ian Turner

(School of Mathematical Sciences, Queensland University of Technology)

Computational Modelling for Industry

The QUT porous media modelling group has developed a number of fruitful collaborations with industry partners over the last 20 years where large-scale computations were utilised to investigate and optimise operations. In this lecture I will reflect on the rich experience of working with industry — from commercial research to work integrated learning for final year students. A pleasing outcome is the impact our research has had on industry practices. A selection of our past modelling projects will be reviewed, including:

  • Forecasting the value of a southern pine plantation.
  • Drying of lignocellulosic materials.
  • Groundwater modelling.

I will also provide a brief survey of the computational solution strategies employed for the models.

Brief Biography: Ian Turner is a professor of computational mathematics in the School of Mathematical Sciences at the Queensland University of Technology. His main research interests are in the fields of computational mathematics and numerical analysis, where he has over thirty years experience in solving systems of coupled, nonlinear partial differential equations that govern flow in porous media. He has published over 250 research articles in a wide cross section of journals spanning science and engineering, and his multidisciplinary research demonstrates a strong interaction with industry. He is also a former Head of School of Mathematical Sciences at QUT. Recently, Professor Turner was named in the 2015, 2016 Thomson Reuters and 2017 Clarivate Analytics Web of Science list of Highly Cited Researchers.
