Some properties of para-Kähler–Walker metrics

Abstract

Some properties of para-Kähler-Walker metrics by Mustafa Özkan (Ankara) and Murat İs ¸can (Erzurum)

On Walker 4-manifolds with pseudo bi-Hermitian structures

“…Such Walker manifolds are intensively investigated (see, e.g. [4][5][6][7][8][9][10][11][12]14,15]).…”

On Four-Dimensional Paracomplex Structures with Norden Metrics

“…For an application of such a 4-dimensional Walker metric (see [9]). Since the observation of the existence of almost paracomplex structures on Walker 4-manifolds in a paper [20], the Walker 4-manifolds have been intensively studied, e.g., [1,3,4,8,13,14,16,20,22].…”
