On complex Landsberg and Berwald spaces

Abstract

In this paper, we study complex Landsberg spaces and some of their important subclasses. The tools of this study are the Chern–Finsler, Berwald, and Rund complex linear connections. We introduce and characterize the class of generalized Berwald and complex Landsberg spaces. The intersection of these spaces gives the so-called G -Landsberg class. This last class contains two other kinds of complex Finsler spaces: strong Landsberg and G -Kähler spaces. We prove that the class of G -Kähler spaces coincides with complex Berwald spaces, in Aikou’s (1996) [1] sense, and it is a subclass of the strong Landsberg spaces. Some special complex Finsler spaces with ( α , β ) -metrics offer examples of generalized Berwald spaces. Complex Randers spaces with generalized Berwald and weakly Kähler properties are complex Berwald spaces.
