Ricci Curvature of Finsler Metrics by Warped Product
… we consider a class of Finsler metrics using the warped product notion introduced by B. Chen, Z. Shen and L. Zhao (2018), with another “warping”, one that is consistent with the form of metrics modeling static spacetimes and simplified by spherical symmetry over spatial coordinates, which emerged …

Ricci flow on 3-manifolds with symmetry
… we proved that for a 3-manifold S2 x S1 with warped product metric, the isoperimetric ratio on the base manifold S2 has a low positive bound away from zero, if the scalar curvature on the 3-manifold is positive. We also obtained a monotonicity result under the condition that the length of the …

Aspects Of The Ricci Flow
… with the Ricci flow on a manifold with a warped product structure. Interestingly, that led to a dual problem of studying more abstract flows. Using the monotone framework, we derive several estimates for the adapted heat conjugate fundamental solution which include an analog of G. …

Supersymmetric backgrounds of M-theory and AdS4/CFT3 correspondence
… solutions of d = 11 supergravity consisting of a warped product of four-dimensional anti-de-Sitter space with a sevendimensional Riemannian manifold Y7. We show that the necessary and sufficient conditions for supersymmetry can be phrased in terms of a local SU(2)-structure on Y7. Solutions with …
