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.

Alcinda Honwana: Youth Protests Main Mechanism against Regime
2015-05-25

Prof Alcinda Honwana

"Enough is Enough!": Youth Protests and Political Change in Africa (speech) 

The Centre for Africa Studies at the UFS hosted an interdisciplinary project on the Bloemfontein Campus from 20-22 May 2015.

The project, entitled Contemporary Modes of Othering: Its Perpetuation and Resistance, looked at different perspectives, representations, and art forms of otherness, how it is perceived, and how it is resisted.

The annual Africa Day Memorial Lecture was held on Thursday evening 21 May 2015 at the CR Swart Auditorium. Guest speaker Prof Alcinda Honwana addressed the subject of ‘Youth Protests and Political Change in Africa’.

“Youth now seem able to display what they don’t want, rather than what they do want,” Honwana said in her opening remarks. “Thus, we see the young driven to the streets to protest against regimes.”
 
Honwana shed some light on recent examples of youth protests in Africa that have enjoyed global attention. Looking at the protests in Tunisia (2010), Egypt (2011), Senegal (2012), and Burkina Faso (2014), it is clear that these events in northern and western Africa have inspired others globally. Yet, Honwana stated that, despite these protests, no social economic change has been seen, and has left dissatisfaction with new governments as well.

“Once regimes fall… young activists find themselves more divided, it seems…

“Which leaves the question: Will street protests remain young people’s main mechanism to avert those in power?”

Background on Prof Alcinda Honwana:

Alcinda Honwana is currently Visiting Professor of Anthropology and International Development at the Open University (UK). She was chair in International Development at the Open University, and taught Anthropology at the University Eduardo Mondlane in Maputo, the University of Cape Town in South Africa, and the New School for Social Research in New York. She was programme director at the Social Science Research Council in New York, and worked for the United Nations Office for Children and Armed Conflict. Honwana has written extensively on the links between political conflict and culture, and on the impact of violent conflict on children and youth, conducting research in Mozambique, the Democratic Republic of the Congo, Angola, Colombia, and Sri Lanka. Her latest work has been on youth and social change in Africa, focusing on Mozambique, Senegal, South Africa, and Tunisia.

Honwana’s latest books include:

• Youth and Revolution in Tunisia (2013); 
• Time of Youth: Work, Social Change, and Politics in Africa (2012);
• Child Soldiers in Africa (2006);
• Makers and Breakers: Children and Youth in Postcolonial Africa (2005, co-edited).

Honwana was awarded the prestigious Prince Claus Chair for Development and Equity in the Netherlands in 2007.
