The Ricci flow on noncommutative two-tori
noncommutative two-tori Ricci flow High Energy Physics - Theory
2011/10/9
Abstract: In this paper we construct a version of Ricci flow for noncommutative 2-tori, based on a spectral formulation in terms of the eigenvalues and eigenfunction of the Laplacian and recent result...
Metric Compatible or Noncompatible Finsler-Ricci Flows
Finsler geometry, Ricci flows, geometric evolution
2011/9/6
There were elaborated different models of Finsler geometry using the Cartan (metric compatible), or Berwald and Chern (metric non朿ompatible) connections, the Ricci flag curvature etc. In a seri...

2011/9/7
We have considered the generalized holographic and generalized Ricci dark energy models for acceleration of the universe. If the universe filled with only GHDE/GRDE the corresponding decel-eration par...

2011/9/6
We have considered the flat FRW model of the universe which is filled with the combination of dark matter and dark energy. Here we have considered two types of dark energy models: (i)Generalized holog...

Do the Ricci and energy-momentum tensors have "duality'' in the context of their Lie symmetries?
Ricci energy-momentum tensors
2010/12/20
The Ricci and energy-momentum tensors have the same algebraic sym-metries. In the Einstein equations they look “dual” to each other, in that interchang-ing them and inverting the gravitational couplin...

Timelike and Spacelike Ricci Collineation Vectors in String Fluid
Ricci Collineation String String Fluid
2010/4/13
We study the consequences of the existence of timelike and spacelike Ricci collineation vectors (RCVs) for string fluid in the context of general relativity. Necessary and sufficient conditions are de...
Ricci defects of microlocalized Einstein metrics
Ricci defects microlocalized Einstein metrics
2014/4/3
The third paper in the series with I. Rodnianski on rough solutions to the Einstein vacuum equations. We prove an important result which was needed in our second paper.
