Hermitian curvature flow
Witryna2 gru 2013 · The Chern–Ricci flow is an evolution equation of Hermitian metrics by their Chern–Ricci form, first introduced by Gill. Building on our previous work, we investigate this flow on complex surfaces. We establish new estimates in the case of finite time non-collapsing, analogous to some known results for the Kähler–Ricci flow. WitrynaHERMITIAN CURVATURE FLOW 3 Kahler.

In this paper, we study the existence of conformal metrics with constant holomorphic d-scalar curvature and the prescribed holomorphic d-scalar curvature problem on closed, connected almost Hermitian manifolds of dimension n ⩾ 6. In addition, we obtain an application and a variational formula for the associated … Witryna15 kwi 2024 · In this paper we establish partial structure results on the geometry of compact Hermitian manifolds of semipositive Griffiths curvature. We show that after appropriate arbitrary small deformation of the initial metric, the null spaces of the Chern–Ricci two-form generate a holomorphic, integrable distribution. This distribution …

WitrynaWe call Θ(g) the torsion-twisted Chern–Ricci curvature. The flow (1) is a member of a family of Hermitian Curvature Flows (HCFs), where Q(T) is taken to be an arbitrary tensor quadratic in T, introduced by Streets and Tian in [23], generalising the Kahler–Ricci flow to non-Ka¨hler Hermitian manifolds(see [25, §3] and references … bo jackson pro careerWitrynaThe Riemann curvature tensor is also the commutator of the covariant derivative of an arbitrary covector with itself:;; =. This formula is often called the Ricci identity. This is the classical method used by Ricci and Levi-Civita to obtain an expression for the Riemann curvature tensor. This identity can be generalized to get the commutators for two … bo jackson pro football statsWitrynaWe study an analogue of the Calabi flow in the non-Kähler setting for compact Hermitian manifolds with vanishing first Bott–Chern class.
