Description

Lecture 3 - Invariant polynomials and cyclic decomposition

  • Motivation: structure of the A matrix, towards transmission zeros and feedback
  • Annihilating polynomials
  • MAP (minimal annihilating polynomial) of a space, of a vector
  • Invariant subspaces
  • Cyclic subspaces (invariant)
  • RMAP (relative annihilating polynomial) modulo an invariant subspace
  • Comprimeness and direct sum decomposition
  • Main theorem on cyclic decomposition and invariant polynomials
