Stability of Kähler-Ricci Flow [PDF]

open access: yesJournal of Geometric Analysis, 2009
We prove the convergence of K hler-Ricci flow with some small initial curvature conditions. As applications, we discuss the convergence of K hler-Ricci flow when the complex structure varies on a K hler-Einstein manifold.

The Soliton-Ricci Flow with variable volume forms

open access: yesComplex Manifolds, 2016
We introduce a flow of Riemannian metrics and positive volume forms over compact oriented manifolds whose formal limit is a shrinking Ricci soliton. The case of a fixed volume form has been considered in our previouswork.We still call this new flow, the ...

Gradient flow of Einstein-Maxwell theory and Reissner-Nordström black holes

open access: yesJournal of High Energy Physics, 2023
Ricci flow is a natural gradient flow of the Einstein-Hilbert action. Here we consider the analog for the Einstein-Maxwell action, which gives Ricci flow with a stress tensor contribution coupled to a Yang-Mills flow for the Maxwell field.

Monotone Volume Formulas for Geometric Flows [PDF]

open access: yes, 2010
We consider a closed manifold M with a Riemannian metric g(t) evolving in direction -2S(t) where S(t) is a symmetric two-tensor on (M,g(t)). We prove that if S satisfies a certain tensor inequality, then one can construct a forwards and a backwards ...

Metric Perspectives of the Ricci Flow Appliedto Disjoint Unions

open access: yesAnalysis and Geometry in Metric Spaces, 2014
In this paper we consider compact, Riemannian manifolds M1, M2 each equipped with a oneparameterfamily of metrics g1(t), g2(t) satisfying the Ricci flow equation.

Cobordism, singularities and the Ricci flow conjecture

open access: yesJournal of High Energy Physics, 2023
In the following work, an attempt to conciliate the Ricci flow conjecture and the Cobordism conjecture, stated as refinements of the Swampland distance conjecture and of the No global symmetries conjecture respectively, is presented.

On the stability of harmonic maps under the homogeneous Ricci flow

open access: yesComplex Manifolds, 2018
In this work we study properties of stability and non-stability of harmonic maps under the homogeneous Ricci flow.We provide examples where the stability (non-stability) is preserved under the Ricci flow and an example where the Ricci flow does not ...

Characterizations of Trivial Ricci Solitons

open access: yesAdvances in Mathematical Physics, 2020
Finding characterizations of trivial solitons is an important problem in geometry of Ricci solitons. In this paper, we find several characterizations of a trivial Ricci soliton.

Fractional nonholonomic Ricci flows [PDF]

open access: yesChaos, Solitons & Fractals, 2012
We formulate the fractional Ricci flow theory for (pseudo) Riemannian geometries enabled with nonholonomic distributions defining fractional integro-differential structures, for non-integer dimensions. There are constructed fractional analogs of Perelman's functionals and derived the corresponding fractional evolution (Hamilton's) equations.
