Joint Seminar of Analysis, Geometry and Topology Department and International Center for Mathematical Sciences – Sofia (ICMS-Sofia) Concircularly Semi-Symmetric Metric Connection Miroslav Maksimović University of Priština in Kosovska Mitrovica, Kosovska Mitrovica, Serbia, and Institute of Mathematics and Informatics, Bulgarian Academy of Sciences, Bulgaria September 30, 2025, 11:00 h – room 403 Abstract. A concircularly semi-symmetric metric connection is a special class of semi-symmetric metric connection when its generator is a concircular vector. In this talk, we will present results on this connection on pseudo-Riemannian manifolds, and in particular, we will observe the application to Lorentzian manifolds and the theory of relativity. We demonstrate that a Lorentzian manifold reduces to a GRW space-time when the generator of the observed connection is a unit timelike vector. [...]
