Popis: | Given an observable pair of matrices ( C , A ) we consider the manifold of ( C , A )-invariant subspaces having a fixed Brunovsky–Kronecker structure. Using Arnold techniques we obtain the explicit form of a miniversal deformation of a marked ( C , A )-invariant subspace with respect to the usual equivalence relation. As an application, we obtain the dimension of the orbit and we characterize the structurally stable subspaces (those with open orbit). |
