Smale’s spectral decomposition theorem


Let M be a compactPlanetmathPlanetmath differentiable manifold and let f:MM be an Axiom A diffeomorphism. The nonwandering set Ω of f can be partitioned into a finite number of compact topologically transitive blocks, called basic blocks:

Ω=i=1mΛi.

Moreover, each basic block is partitioned into a finite number of compact subblocks Λij, j=1,,mi such that f(Λij)=Λi(j+1) for 1j<mi and f(Λimi)=Λi1, and Λij is topologically mixing for fmi.
