The Ricci flow on noncommutative two-tori
noncommutative two-tori Ricci flow High Energy Physics - Theory
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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...

Do the Ricci and energy-momentum tensors have "duality'' in the context of their Lie symmetries?
Ricci energy-momentum tensors

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...

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...
