Anders Szepessy

The 1989 doctoral thesis submitted at Chalmers University of Technology, titled Convergence of the streamline diffusion finite element method for conservation laws, marked the entry of Anders Szepessy into the field of applied mathematics. Born in 1960, the Swedish mathematician has focused his academic career on numerical analysis and partial differential equations throughout his tenure in Stockholm.

Academic Foundations and Research Focus

Supervised by Claes Johnson, Szepessy developed his expertise in finite element methods during his postgraduate studies. His research addresses numerical solutions for hyperbolic conservation laws, a critical area in applied mathematics. His early publications, including works from 1989 in the Archive for Rational Mechanics and Analysis, explored measure-valued solutions and shock-capturing techniques. This rigorous approach to the convergence of numerical methods established a basis for his subsequent work on the stability of viscous shock waves and rarefaction waves, often collaborating with researchers such as Peter Hansbo, Zhouping Xin, Jonathan Goodman, and Kevin Zumbrun.

Professional Contributions

Szepessy holds a professorship at the KTH Royal Institute of Technology, where he continues to teach and conduct research in numerical analysis. His contributions extend into stochastic differential equations, specifically adaptive weak approximations, as evidenced by his 2001 work with Raúl Tempone and Georgios E. Zouraris. His institutional presence at KTH remains a central component of his career, aligning with the university's role in advancing computational mathematics in Scandinavia.

Recognition and Institutional Standing

The mathematical community recognized his body of work through the Wallenberg Prize in 1995. Beyond his internal university responsibilities, he engaged with the broader scientific community as an invited speaker at the International Congress of Mathematicians in Madrid in 2006. In 2007, his ongoing commitment to the discipline resulted in his election as a member of the Royal Swedish Academy of Sciences, solidifying his role within the Swedish scientific establishment.
