معرفی
Prof. Dr. Matthias Keller is a leading researcher in discrete spectral theory and graph analysis, affiliated with the Institute of Mathematics at the University of Potsdam since 2015. His work bridges geometric properties of graphs with spectral theory, focusing on Dirichlet forms, Schrödinger operators, and functional inequalities.
- Key Collaborations: Daniel Lenz, Radoslaw Wojciechowski, Yehuda Pinchover
- Books Authored: Graphs and Discrete Dirichlet Spaces (Springer, 2021)
His research explores non-positively curved graphs, stochastic completeness, and magnetic sparseness. Recent projects include optimal Hardy inequalities and spectral analysis of fractional Laplacians.
Scientific Awards:
- Swiss Fellowship (2023)
- Golda Meir Fellowship (2012-2013)
- Klaus Murmann PhD Fellowship (2007-2010)
He advises PhD and Master’s students such as Yannik Thomas, Matti Richter, and Philipp Bartmann, while maintaining active roles in DFG-funded projects and international workshops.
