We studied complex and real hypersurfaces immersed in locally conformal Kähler manifolds. We have obtained conditions for the immersions, if the manifolds admit existence of such complex hypersurfaces that are orthogonal to both Lee and anti-Lee vec

Differential Geometry of Special Mappings

Autor: Mikeš Josef, et al

The collective monograph is devoted to geodesic mappings (i.e. diffeomorphisms preserving geodetics) of Riemannian manifolds and their generalizations. The book also shows related geometric issues and it consists of 18 chapters. The first and the sec
