Franz Lehner

Franz Lehner is an Associate Professor at the Institute of Discrete Mathematics, Graz University of Technology. His research focuses on operator algebras, operator spaces, harmonic analysis, and free probability theory.

He actively develops software packages for combinatorial probability and noncommutative probability in FriCAS, including functionality for moments, cumulants, and orthogonal polynomials. His work connects probability theory with algebraic structures like Jacobi parameters and continued fractions.

Key contributions include algorithmic implementations for free probability operations and mathematical software tools for computational analysis. He maintains a personal webpage with technical details about his projects.
