Håkan Eliasson , also quoted by LH Eliasson, (born July 13, 1952 ) is a Swedish mathematician.

Life

Eliasson received his doctorate in 1984 from the University of Stockholm under Jürgen Moser (Hamiltonian systems with Poisson commuting integrals). He was a professor at the Royal Institute of Technology in Stockholm and is a professor at the University of Paris VII (Denis Diderot) and at the Institut de mathématiques de Jussieu of the Universities of Paris VI and VII and the CNRS.

He deals with dynamic systems, e.g. B. quasi-periodic motion, the small denominator problem in perturbation theory, KAM theory and multiscale analysis in perturbation theory, Hamiltonian partial differential equations, and also localization and diffusion in quasi-periodic Schrödinger operators.

In 2005 and 2012 he was at the Institute for Advanced Study .

In 1990 he received the Wallenberg Prize of the Swedish Mathematical Society, the Salem Prize in 1995 , the Eva and Lars Gårding Prize in 2007 and the Sophie Germain Prize in 2008 .

In 1998 he was invited speaker at the International Congress of Mathematicians in Berlin ( Reducibility and point spectrum for linear quasi-periodic skew-products ).

2012–2017 he was co-editor of Acta Mathematica .
