Symmetry algebra and block diagonalizability of linear quasiperiodic systems of block-triangular form. (Russian) Zbl 0825.58037
Sufficient conditions are established for the reduction of linear quasiperiodic systems to a block-diagonal form. The symmetry algebra of linear systems and its relation to diagonalizability is studied.
