This year's Mathematics Week will take place from Monday 6 to 15 March 2023 and will focus on the following theme: "Mathematics à la carte". To this end, the University of Guyana is offering lectures in Amphitheatre A as well as distance learning.
L he aim of Mathematics Week is to offer all pupils in schools, collèges and lycées, as well as their parents, the opportunity to learn about mathematics, an up-to-date, lively and attractive image of mathematics.
Monday 06 March 2023, 16.00-18.00, Amphi A
Speaker : Mr Alain PAVE - Professor Emeritus, Biology-Mathematics-Modelling | University of Lyon 1 (Videoconference)
Title : The logistic model to introduce modelling.
Summary: This demographic model provides a simple introduction to the principles of modelling, while avoiding technical difficulties.
Wednesday 08 March 2023, 12.15-13.30, Amphi A
Speaker: Mr Abdennebi OMRANE - Professor of Mathematics | DFR ST, University of Guyana
Title : A la carte mathematical models.
Summary: This talk will provide an introduction to mathematical modelling. This will be followed by an introduction to a number of classical mathematical models that correspond to different situations in biology and ecology, and address different problems that are continuous over time. In each case, we will try to explain the usefulness of the model in question and the assumptions under which it operates, since no model is perfect.
Friday 10 March 2023, 12.15-13.30, Amphi A
Speaker : Mr Stéphane THOMAS - Associate Professor of Mathematics | INSPE, University of Guyana
Title : Hilbert's third problem and the Banach-Tarski paradox.
Summary: In secondary school, the calculation of polygonal areas can be taught by cutting out and it is easy to explain to our pupils where the classic formulae come from. However, when it comes to calculating volumes, we come up against a number of difficulties (the volume of a pyramid in the general case, for example). The aim of this presentation is to explain the mathematical origins of these difficulties, which were only clarified in the 20th century:
- Calculating the volume of a pyramid in Euclid's elements
- Hilbert's Third Problem
- Banach-Tarski paradox
