SAMS Congress 2022

65th SAMS Congress
06-08 December 2022
Stellenbosch University

Because of the considerable overlap, the SANUM and Differential Equations (and Machine Learning) sessions have been combined.

Numerical and Applied Mathematics (SANUM) and Differential Equations

Organisers: Andre Weideman (weideman@sun.ac.za), Kailash Patidar (kpatidar@uwc.ac.za), Edgard Ngounda (NgoundaE@ufs.ac.za), and Yves Semegni (Yves.Semegni@nwu.ac.za)

Session info: Thiss session invites talks on all aspects of numerical and applied mathematics. This includes, but is not limited to, numerical solution of ordinary, fractional, stochastic, and partial differential equations, numerical linear algebra and optimization, quadrature and integral transforms, computational fluid dynamics, mathematical finance, and modelling of physical systems.
