Toric extremal Kähler-Ricci solitons are Kähler-Einstein

Complex Manifolds, 2017
In this short note, we prove that a Calabi extremal Kähler-Ricci soliton on a compact toric Kähler manifold is Einstein. This settles for the class of toric manifolds a general problem stated by the authors that they solved only under some curvature ...

Matter field Kähler metric in heterotic string theory from localisation

Journal of High Energy Physics, 2018
We propose an analytic method to calculate the matter field Kähler metric in heterotic compactifications on smooth Calabi-Yau three-folds with Abelian internal gauge fields.

The three‐dimensional Seiberg–Witten equations for 3/2$3/2$‐spinors: A compactness theorem

Mathematische Nachrichten, Volume 298, Issue 10, Page 3331-3375, October 2025.
Abstract The Rarita‐Schwinger–Seiberg‐Witten (RS–SW) equations are defined similarly to the classical Seiberg–Witten equations, where a geometric non–Dirac‐type operator replaces the Dirac operator called the Rarita–Schwinger operator. In dimension 4, the RS–SW equation was first considered by the second author (Nguyen [J. Geom. Anal. 33(2023), no. 10,

Quasi-Statistical Manifolds with Almost Hermitian and Almost Anti-Hermitian Structures

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
Let (M, g, ∇) be a 2n-dimensional quasi-statistical manifold that admits a pseudo-Riemannian metric g (or h) and a linear connection ∇ with torsion. This paper aims to study an almost Hermitian structure (g, J ) and an almost anti-Hermitian structure (h,

Symptom correlation and spatial distribution of inflammatory mediators in pulpitis—A preliminary study

International Endodontic Journal, Volume 58, Issue 10, Page 1565-1581, October 2025.
Abstract Aim To evaluate the association of inflammatory mediators with clinical signs and symptoms and their spatial distribution in teeth with pulpitis. Methodology Fifty permanent teeth from adults with clinical diagnoses of normal pulp (n = 17), reversible pulpitis (n = 13) and symptomatic/asymptomatic irreversible pulpitis (n = 20), were recruited.

A Kähler Einstein structure on the tangent bundle of a space form

International Journal of Mathematics and Mathematical Sciences, 2001
We obtain a Kähler Einstein structure on the tangent bundle of a Riemannian manifold of constant negative curvature. Moreover, the holomorphic sectional curvature of this Kähler Einstein structure is constant.

Special geometry on the moduli space for the two-moduli non-Fermat Calabi–Yau

Physics Letters B, 2018
We clarify the recently proposed method for computing a special Kähler metric on a Calabi–Yau complex structure moduli space using the fact that the moduli space is a subspace of a particular Frobenius manifold. We use this method to compute a previously

On Warped Product Pointwise Pseudo-Slant Submanifolds of LCK-Manifolds and Their Applications

Axioms
The concept of pointwise slant submanifolds of a Kähler manifold was presented by Chen and Garay. This research extends this notion to a more general setting, specifically in a locally conformal Kähler manifold. We study the pointwise pseudo-slant warped

Frobenius integrability of certain $p$-forms on singular spaces

Comptes Rendus. Mathématique
Demailly proved that on a smooth compact Kähler manifold the distribution defined by a holomorphic $p$-form with values in an anti-pseudoeffective line bundle is always integrable. We generalise his result to compact Kähler spaces with klt singularities.

Properties of the quasi-conformal curvature tensor of Kähler-Norden manifolds [PDF]

Mathematica Moravica, 2014
The object of the present paper is to study quasi-conformally flat and parallel quasi-conformal curvature tensor of a Kähler-Norden manifold. Besides this we also study quasi-conformally semisymetric Kähler-Norden manifolds.
