The Energy-Momentum tensor on low dimensional $\Spinc$ manifolds
Spinc structures Dirac operator eigenvalues Energy-Momentum tensor compact surfaces isometric immersions
2012/4/18
On a compact surface endowed with any $\Spinc$ structure, we give a formula involving the Energy-Momentum tensor in terms of geometric quantities. A new proof of a B\"{a}r-type inequality for the eige...
On electromagnetism and generalized energy-momentum tensor of the electromagnetic field in spaces with Finsler geometry
On electromagnetism generalized energy-momentum tensor electromagnetic field spaces Finsler geometry
2011/1/20
By using variational calculus and exterior derivative formalism, we proposed in [30] and [11] a new geometric approach to electromagnetism in pseudo-Finsler spaces.
The Energy-Momentum tensor on $Spin^c$ manifolds
The Energy-Momentum tensor $Spin^c$ manifolds
2010/11/8
On $Spin^c$ manifolds, we study the Energy-Momentum tensor associated with a spinor field. First, we give a spinorial Gauss type formula for oriented hypersurfaces of a $Spin^c$ manifold. Using the no...
