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.

Alumni Voices heralds in festive season with Karl Jenkins production

2013-11-20

The Alumni Voices Chamber Choir, affiliated to the Alumni office of the University of the Free State, heralds in the festive season with a Christmas production with the Drakensberg Boys’ Choir.

Date: 23 and 24 November 2013
Time: 19:30 (23 November 2013)
16:00 (24 November 2013)
Venue: Odeion
Cost: R120

The production by the two choirs, under the direction of Leona Geldenhuys (Alumni Voices) and Johann van der Sandt (Drakensberg Boys’ Choir), is a compilation of new Christmas music by Karl Jenkins.

Two cycles, Stella Natalis, made up from new compositions, and Joy to the World, compiled from well-known traditional Christmas music, are combined in this production.

Stella Natalis (Star of Birth or Star of Origin) celebrates the different aspects of Christmas – Celebro – celebrations, Lullay – the sleeping child, Dona nobis pacem – message of peace, and Jubilate Deo – thanksgiving, forms part of the programme.

The part: JOY TO THE WORLD also includes traditional Christmas music. This fresh and vibrant arrangement of In dulci jubilo, Go Tell it on the Mountain, Silent Night, O Jesu so sweet, Son of Maria and The Virgin Mary had a Baby boy, all new arrangements by Karl Jenkins, promises to be an exciting experience.

This work, which conveys the Christmas message of peace, goodwill and compassion, as well as new beginnings, evokes a colour palette of sound filled with exciting musical inspiration.

The work was written for mixed choir, as well as for an optional choir suitable for children’s voices, trumpet soloist, keyboard, percussion and string ensemble.

The trumpet soloist is Paul Loeb van Zuilenburg, with Johan Cromhout as pianist. Members of the Free State Symphony Orchestra complete the picture.
