Convergence of the weak K\"ahler-Ricci Flow on manifolds of general type

, 2019
We study the K\"ahler-Ricci flow on compact K\"ahler manifolds whose canonical bundle is big. We show that the normalized K\"ahler-Ricci flow has long time existence in the viscosity sense, is continuous in a Zariski open set, and converges to the unique

Water or Energy Supply Driven Change in Moisture Availability Switches the Slope Direction Between Shallow Soil Moisture and Actual Evapotranspiration: Interpretation Within the Context of the Complementary Relationship

Water Resources Research, Volume 61, Issue 8, August 2025.
Abstract Ecosystem moisture availability (ma) increases as the landscape becomes more energy‐limited, driven by either rising water supply or declining energy supply. This study aimed to assess the influence of water and energy supply changes on ma and its effects on actual evapotranspiration (E) and shallow soil moisture (S) dynamics. We simulated the

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.

Global eigenfamilies on closed manifolds

Journal of the London Mathematical Society, Volume 112, Issue 2, August 2025.
Abstract We study globally defined (λ,μ)$(\lambda,\mu)$‐eigenfamilies on closed Riemannian manifolds. Among others, we provide (non‐)existence results for such eigenfamilies, examine topological consequences of the existence of eigenfamilies and classify (λ,μ)$(\lambda,\mu)$‐eigenfamilies on flat tori. It is further shown that for f=f1+if2$f=f_1+i f_2$

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,

Non trivial examples of coupled equations for K\"ahler metrics and Yang-Mills connections

, 2011
We provide non trivial examples of solutions to the system of coupled equations introduced by M. Garc\'ia-Fern\'andez for the uniformization problem of a triple $(M,L,E)$ where $E$ is a holomorphic vector bundle over a polarized complex manifold $(M,L)$,
