The author constructs the gauged Skyrme model by introducing the skyrmion bundle as follows: instead of considering maps U:MSUNF he thinks of the meson fields as of global sections in a bundle B(M,SUNF,G)=P(M,G)×GSUNF. 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 NF6, one has H*(EG×GSUNF)H*(SUNF)GS(G̲*)H*(SUNF)H*(BG)H*(SUNF), where EG(BG,G) is the universal bundle for the Lie group G and G̲ is the Lie algebra of G.
