On Kähler-like and G-Kähler-like almost Hermitian manifolds [PDF]

Complex Manifolds, 2020
We introduce Kähler-like, G-Kähler-like metrics on almost Hermitian manifolds. We prove that a compact Kähler-like and G-Kähler-like almost Hermitian manifold equipped with an almost balanced metric is Kähler.

Special Hermitian metrics on Oeljeklaus-Toma manifolds [PDF]

Bulletin of the London Mathematical Society, 2020
Oeljeklaus-Toma (OT) manifolds are higher dimensional analogues of Inoue-Bombieri surfaces and their construction is associated to a finite extension $K$ of $Q$ and a subgroup of units $U$. We characterize the existence of pluriclosed metrics (also known as strongly K\" ahler with torsion (SKT) metrics) on any OT manifold $X(K, U)$ purely in terms of ...

SINGULAR HERMITIAN METRICS WITH ISOLATED SINGULARITIES [PDF]

Nagoya Mathematical Journal, 2022
AbstractIn this paper, we study the coherence of a higher rank analogue of a multiplier ideal sheaf. Key tools of the study are Hörmander’s $L^2$ -estimate and a singular version of a Demailly–Skoda-type result.

Perfect Hermitian rank-metric codes [PDF]

The Art of Discrete and Applied Mathematics
This study investigates Hermitian rank-metric codes, a special class of rank-metric codes, focusing on perfect codes and on the analysis of their covering properties. Firstly, we establish bounds on the size of spheres in the space of Hermitian matrices and, as a consequence, we show that non-trivial perfect codes do not exist in the Hermitian case. We

Polar supermultiplets, hermitian symmetric spaces and hyperkähler metrics [PDF]

Journal of High Energy Physics, 2007
We address the construction of four-dimensional N=2 supersymmetric nonlinear sigma models on tangent bundles of arbitrary Hermitian symmetric spaces starting from projective superspace. Using a systematic way of solving the (infinite number of) auxiliary field equations along with the requirement of supersymmetry, we are able to derive a closed form ...

Plurisigned hermitian metrics

Transactions of the American Mathematical Society, 2023
Let ( X , ω ) (X,\omega ) be a compact hermitian manifold of dimension n n . We study the asymptotic behavior of Monge-Ampère volumes ∫ X ( ω + d d c φ ) n

Nonpositively curved Hermitian metrics on product manifolds [PDF]

Proceedings of the American Mathematical Society, 2010
In this article, we classify all the Hermitian metrics on a complex product manifold with nonpositive holomorphic bisectional curvature. It is a generalization of a result by Zheng.
