معرفی
Christian Lange is a Research Fellow at the Mathematical Institute of Ludwig-Maximilians-Universität München (LMU Munich). He holds a PhD and specializes in differential geometry, geometric topology, and orbifold theory. His current teaching includes a lecture on Riemannian Geometry (Summer 2025), focusing on advanced topics in geometric analysis.
His research emphasizes orbifold structures, geodesic flows, and curvature properties. Notable contributions include studies on closed geodesics on orbifolds, systolic inequalities, and the interplay between billiard dynamics and Alexandrov geometry. Lange collaborates internationally, addressing problems in Riemannian geometry, symplectic topology, and geometric group actions.
Publications highlight work on orbifold curvature bounds, Besse metrics, and deformations of Finsler structures. His 2023 paper in Journal of the European Mathematical Society proved a diameter gap theorem for sphere quotients. He also explores connections between Lorentzian metrics and Lipschitz regularity in geometric analysis.
Supported by institutions like the Simons Foundation, Lange’s work bridges pure geometry with applications in topology and mathematical physics. His research group focuses on geometry and topology, contributing to foundational questions in differential and metric geometry.
