The next meeting of the Joint Seminar of Analysis, Geometry and Topology Department will be held
on February 15, 2022, at 1:00 pm (UTC+2) via Zoom.
A talk on:

Kähler Manifolds of Quasi-constant Holomorphic Sectional Curvature and Generalized Sasakian Space Forms

will be delivered by Cornelia-Livia Bejan,  “Gheorghe Asachi” Technical University of Iasi, Romania.

Everybody is invited.

Abstract. Two geometric notions, namely Kähler manifolds of quasi-constant holomorphic sectional curvature and generalized Sasakian space forms, are related to each other, for the first time. Some conditions under which each of these structures induces the other one, are provided here. Several results are obtained on direct products (which are special cases of Naveira’s classification), warped products or hypersurfaces of manifolds and relevant examples are included. A result of Niebergall and Ryan is generalized here. Some necessary and sufficient conditions for Einsteinian hypersurfaces are given at the end. The talk is based on a joint work with S. Guler.
