On a Theorem of Wang for Complex Homogeneous Manifolds

David N. Pham

In \cite{Wang1954}, Wang proved (among other things) a sufficiency result for a compact homogeneous manifold to admit a -invariant complex structure. In this note, we give…

On the Chern-Ricci form of a twisted almost Kähler structure

David N. Pham, Fei Ye

Let be an almost Kähler manifold. For any smooth function on , one can associate an automorphism $ψ\in \mbox{Aut}(TM)$ for which the Kähler form is invariant. Us…

Twists, Codazzi Tensors, and the -sphere

David N. Pham

Let be an almost Hermitian manifold. Given an automorphism , the existing structure can be twisted to obtain a new almost Hermitian manifold $(M,…

Left-invariant Hermitian connections on Lie groups with almost Hermitian structures

David N. Pham, Fei Ye

Left-invariant Hermitian and Gauduchon connections are studied on an arbitrary Lie group equipped with an arbitrary left-invariant almost Hermitian structure $(\langle\cdot,\cd…

Left invariant nearly pseudo-Kähler structures and the tangent lie group

David N. Pham

Let be a Lie group, and let be a left invariant almost pseudo-Hermitian structure on . It is shown that if is also nearly pseudo-Kähler, then the tangent bun…

The Lie groupoid analogue of a symplectic Lie group

David N. Pham

A symplectic Lie group is a Lie group with a left-invariant symplectic form. Its Lie algebra structure is that of a quasi-Frobenius Lie algebra. In this note, we identify the group…
