In particular the canonical decomposition of the unobservable subspace as a direct sum of cyclic subspaces as well as the conditions for this subspace to be spectral for the system matrix is studied. This definition makes sense, because CD/ maps A into 6(/) and tf maps B into 6(/).

There are subtle phenomena in Macdonald theory (the positivity of the composition Kostka functions ) that arise in the so-called stable limit, that is, they describe properties of objects that are associated to certain limits of polynomial functions when the number of variables approaches infinity. The structural properties of the unobservable subspace are explored. A subspace is a vector space that is entirely contained within another vector space. The stable coding subspaces were identified by applying PCA to time-averaged voxel activity patterns.
