Peter Sjögren
Professor emeritus at
Chalmers, Mathematical Sciences
Peter Sjögren is the leader of the research group in Harmonic Analysis and Partial Differential Equations, and he works with partners in several countries. His research deals mostly with harmonic analysis in settings given by orthogonal polynomials and orthogonal expansions, often classical ones. The idea is to describe physical and other phenomena, described by partial differential equations, in situations where classical Fourier analysis is not adequate. He is an editor of the journal Arkiv för matematik. A large part of his teaching concerns basic Fourier analysis.
