Stefan Richter

Stefan Richter is a Professor of Mathematics in the Department of Mathematics at the University of Tennessee, Knoxville. He holds a Ph.D. from the University of Michigan and a degree from the Christian-Albrechts-Universität in Kiel, Germany. His research focuses on operator theory and complex analysis, with emphasis on invariant subspaces, Hilbert function spaces (e.g., Dirichlet space, Drury-Arveson space), and analytic function theory. He has organized conferences like the Southeastern Analysis Meeting (SEAM) and the Hilbert Function Spaces conference. His work explores topics such as cyclicity in function spaces, Toeplitz operators, and multi-variable operator theory.

Research interests include operator theory applications to function spaces, boundary behavior of analytic functions, and structural properties of invariant subspaces. Notable contributions involve characterizing cyclic vectors in Dirichlet-type spaces and analyzing multipliers between function spaces. Richter has also engaged in interdisciplinary collaborations, such as exploring connections with non-commutative analysis through graph transformations.

His academic activities span organizing international conferences (e.g., SEAM 2017), delivering invited lectures at AMS meetings, and maintaining an active publication record in leading journals. His professional contributions are further evidenced by his role in academic service, including editorial work and participation in workshops like the CIRM conference on Hankel operators.
