Prof Johan Meyer, Senior Professor in the Department of Mathematics and Applied Mathematics, says he is looking forward to learning from others in the field during this collaboration.

What do trees, black holes, earthquakes, and time structures have in common? 

The answer to this question is that these, in one way or the other, form the focus of some of the abstracts delivered during the Annual Congress of the South African Mathematical Society. The society has as its main objective the advancement of mathematics in South Africa. 

The Department of Mathematics and Applied Mathematics at the University of the Free State (UFS), in conjunction with the South African Mathematical Society (SAMS 2021), is hosting the 64th Annual Congress of the society this week (29 November to 1 December 2021).

Prof Johan Meyer, Senior Professor in the department, says the congress, which is being conducted online, is focusing on all aspects of mathematics research, including history and teaching.

Learning from others in the field

The congress, which aims to share the latest research results in mathematics, will be attended by staff and students from universities across South Africa as well as abroad. “Anyone from the public is, of course, welcome to attend or even share their results if they are also involved in mathematics research,” adds Prof Meyer. 

He says that he is looking forward to learning from others in the field during this collaboration. 

The congress will include discussions on more than 120 abstracts, covering category theory, algebra, topology, logic; functional analysis and operator theory; finite groups and combinatorial structures; graph theory and combinatorics; lie symmetries and nonlinear differential equations; and applied and numerical mathematics.

Array of interesting topics presented

“It is important in many areas of science and engineering to predict and to simulate rare, random events, the occurrence of which may have negative or even catastrophic consequences. Examples include internet server overflows, mechanical breakdowns, floods, and financial crashes. Rare events can also have a positive effect, triggering for example chemical reactions or driving genetic evolution via random mutations.” Prof Hugo Touchette from Stellenbosch University will be shedding some light on this interesting topic in his presentation on Predicting and simulating rare events.

Prof Jeandrew Brink, Associate Professor in the Department of Mathematics and Applied Mathematics at the UFS, is presenting a plenary session on the topic Determining the geometry of strong field space-times in spite of tacitly assuming the answer during every measurement. In South Africa, state-of-the art pulsar timing data from the MeerKAT telescope will make a considerable contribution to conducting GR orbital tests. Prof Brink comments on how pulsar timing tests differ from tests using gravitational wave detectors, as well as what we can learn from the framework already employed to perform pulsar timing measurements.

Cohesions and Disruptions Forum
2014-07-15

 
The Institute for Reconciliation and Social Justice at the UFS and the Johannes Stegmann Art Gallery, in partnership with the Vryfees, co-presented an artist and academic forum on 18 July 2014.

The forum, ‘Cohesions and Disruptions: Art as a Key to Transformation’, was aptly timed to coincide with Mandela Day. This event formed part of the transformation strategy of the Vryfees arts festival, aiming to support more diversity and cross-cultural, contemporary art programmes.

“Cohesions and Disruptions is part of the new Program for Innovation in Artform Development (PIKO/PIAD),” said Adri Herbert, Director of the Vryfees. “This includes both the cross-cultural OPENLab 2014, a new Australian/South African laboratory for early and mid-career South African artists, and a partnership with the Australian based SituateArt in Festivals initiative, managed by Salamanca Arts Centre in Hobart, Tasmania.”

The forum’s keynote speaker was Lee-Ann Tjunypa Buckskin. She is a Narungga, Wirangu, Wotjobaluk woman from South Australia and Victoria respectively. She is well known throughout the Aboriginal and Torres Strait Islands and broader arts communities. Buckskin’s presentation was titled ‘Building Young Indigenous People’s Lives through Art and Culture in Remote Central Australia.’

Buckskin spoke broadly about her involvement with youngsters – often poverty stricken and sniffing petrol – in remote areas of Australia. She explained how the arts have given the youth a chance at rehabilitation and hope for the future.

After her presentation, she was joined by Dr Willy Nel, lecturer at the UFS School of Education Studies. Dr Nel completed his PhD among the Khomani San in the Kalahari. 

Other forum speakers who presented their work included:
Dr Mari Velonaki, Director of the Centre for Social Robotics at the National Institute for Experimental Art at the University of New South Wales, Sydney;
Dr Nigel Helyer of Sonic Objects; Sonic Architecture, Sydney;
Bec Dean, Curator at Performance Space, Sydney;
Jesse Olivieri, co-founder of Parachutes for Ladies in Sydney; and
Cigdem Aydemir, Vryfees visual artist for 2014.

“Given the histories and present experiences of human rights violations and racial discrimination that indigenous people in Australia and South Africa are subjected to, we are particularly honoured to have Lee-Ann (Buckskin) as a guest speaker,” said Prof Andre Keet, Director of the UFS Institute for Reconciliation and Social Justice.
