Clemens Sämann

Clemens Sämann is an associate professor at the Department of Mathematics, Faculty of Mathematics, University of Vienna. His research focuses on Lorentzian geometry, general relativity, and differential geometry, with significant contributions to spacetime structures, geodesic analysis, and curvature bounds.

Research Interests:

• Lorentzian geometry and causality
• Geodesic completeness in non-smooth spacetimes
• Curvature theorems for Lorentzian length spaces
• Impulsive gravitational waves with cosmological constant Λ

Recent Publications (2024-2016): His work spans timelike curvature bounds, Hausdorff measures in Lorentzian contexts, and mathematical models of spacetime singularities. Key trends include causal differential calculus, metric splitting, and geometric analysis of gravitational wave interactions.
