Abstract: We give an elementary proof of the fact that any 4-dimensional para-Hermitian manifold admits a unique para-Kähler–Weyl structure. We then use analytic continuation to pass from the para-complex to the complex setting and thereby show any 4-dimensional pseudo-Hermitian manifold also admits a unique Kähler–Weyl structure.

Keywords: Weyl geometry; Hermitian manifold; para-Hermitian manifold; pseudo-Hermitian manifold; Kähler manifold; para-Kähler manifold; 4-dimensional geometry
