Olivier Sète

Dr. Olivier Sète is a Professor in the Department of Mathematics at Ulm University, Germany, serving in the Academic Affairs Committee for Mathematics. His research focuses on numerical mathematics, complex analysis, and their applications in astrophysics and natural sciences. Key areas include approximation theory, Helmholtz equation methods, conformal mapping, potential theory, and gravitational lensing modeling.

He has authored/co-authored over 25 publications since 2013, with notable contributions to rational approximation algorithms (e.g., the AAA algorithm), conformal mapping techniques, and stochastic partial differential equations. His work bridges theoretical mathematics with computational methods, addressing challenges in gravitational lensing and wave propagation.

Dr. Sète collaborates with institutions globally, including co-authors like Jörg Liesen and Klaus Schiefermayr. His research has been cited extensively in numerical analysis, complex analysis, and astrophysics. He maintains an active private homepage and is affiliated with zbMATH, MathSciNet, and Google Scholar.

Current projects include advancing conformal mapping for lemniscatic domains and exploring uncertainties in the Helmholtz equation's wavenumber. He advises on academic affairs and contributes to Ulm University's mathematical curriculum development.
