Equivariant cohomology of the skyrmion bundle

Gross, Christian (1997)

Proceedings of the 16th Winter School "Geometry and Physics"

The author constructs the gauged Skyrme model by introducing the skyrmion bundle as follows: instead of considering maps U : M SU N F he thinks of the meson fields as of global sections in a bundle B ( M , SU N F , G ) = P ( M , G ) × G SU N F . For calculations within the skyrmion bundle the author introduces by means of the so-called equivariant cohomology an analogue of the topological charge and the Wess-Zumino term. The final result of this paper is the following Theorem. For the skyrmion bundle with N F 6 , one has H * ( E G × G SU N F ) H * ( SU N F ) G S ( G ̲ * ) H * ( SU N F ) H * ( B G ) H * ( SU N F ) , where E G ( B G , G ) is the universal bundle...

Equivariant differential operators

Reimann, H. M. (2002)

Proceedings of the 21st Winter School "Geometry and Physics"

This paper contains the lectures given by the author at the Winter School on “Geometry and Physics” in Srní 2001. These lectures are based on two recent works of the author with A. Korányi and on a forthcoming paper with K. Johnson and A. Korányi. In the paper results are presented concerning equivariant differential operators on homogeneous spaces (section 1), first order equivariant differential operators on boundaries of symmetric spaces (section 2), the Poisson transform (section 3) and complex...
