Benjamin Delarue

Benjamin Delarue is a mathematician at the University of Paderborn, affiliated with the Faculty of Electrical Engineering, Computer Science and Mathematics and the Institute of Mathematics. He leads the DFG project "Resonances for non-compact locally symmetric spaces" and is a principal organizer of the 2025 conference Lie theory, Spectra and Dynamics. His research focuses on spectral theory, Anosov subgroups, and geometric structures on locally homogeneous manifolds.

• Department: Institute of Mathematics
• Projects: DFG Project, CRC-TRR 358

Research Interests

Delarue investigates spectral properties of pseudo-Riemannian manifolds, dynamics of Anosov representations, and meromorphic extensions of resolvents. His work bridges geometric structures, Lie theory, and quantum-classical correspondence in non-compact symmetric spaces.

• Primary: Spectral Analysis of Lorentzian manifolds
• Secondary: Axiom A flows and Anosov subgroups
• Third: Oscillatory integrals in symplectic geometry

Publication Trends

Recent works emphasize geometric structures for Anosov representations, quantum vs classical resonance analysis, and exponential mixing properties in higher-rank symmetric spaces. Collaborations with Guillarmou, Monclair, and Sanders demonstrate interdisciplinary connections between differential geometry and dynamical systems.

Conference Leadership

• Co-organizer of 2021 Oberwolfach Workshop Anosov³
• Organizer of 2025 Lie theory, Spectra and Dynamics conference

Academic Network

Collaborates with researchers across Europe and North America, including Colin Guillarmou (Université Paris-Saclay), Daniel Monclair (Université Paris-Saclay), and Andrew Sanders (MPI Leipzig). His habilitation thesis "Symmetries in Hyperbolic Dynamics" (2025) solidifies his contributions to the field.
