Abstract
The change in the polarization plane of light vector beams retaining t heir shape (beam modes) under propagation through gradient-index media is evaluated as a topological phase acquired by cyclic and noncyclic evolutions of these beams on their projective Hilbert space (momentum sphere). The polarization changes are evaluated by means of the charac teristic parameters of the light beam selected.
