-dimensional almost-Kähler Lie algebras of constant Hermitian holomorphic sectional curvature are Kähler

Mehdi Lejmi, Luigi Vezzoni

We prove that any -dimensional almost-Kähler Lie algebra of constant Hermitian holomorphic sectional curvature with respect to the canonical Hermitian connection is Kähler.

Closed almost-Kähler 4-manifolds of constant non-negative Hermitian holomorphic sectional curvature are Kähler

Mehdi Lejmi, Markus Upmeier

We show that a closed almost Kähler 4-manifold of globally constant holomorphic sectional curvature with respect to the canonical Hermitian connection is automatically Kä…

On the Chern-Yamabe flow

Mehdi Lejmi, Ali Maalaoui

On a closed balanced manifold, we show that if the Chern scalar curvature is small enough in a certain Sobolev norm then a slightly modified version of the Chern-Yamabe flow~\cite{…

Integrability theorems and conformally constant Chern scalar curvature metrics in almost Hermitian geometry

Mehdi Lejmi, Markus Upmeier

The various scalar curvatures on an almost Hermitian manifold are studied, in particular with respect to conformal variations. We show several integrability theorems, which state t…

On the lower bounds of the L^2-norm of the Hermitian scalar curvature

Julien Keller, Mehdi Lejmi

On a pre-quantized symplectic manifold, we show that the symplectic Futaki invariant, which is an obstruction to the existence of constant Hermitian scalar curvature almost-Kähler…

Cohomologies on hypercomplex manifolds

Mehdi Lejmi, Patrick Weber

We review some cohomological aspects of complex and hypercomplex manifolds and underline the differences between both realms. Furthermore, we try to highlight the similarities betw…
