In Sec. 3 we review the effect of some optical filters and its geometrical representation on the Poincaré sphere. We show that the effect of a phase shifter corresponds to a rotation of the Poincaré sphere, while that of an

WebbPoincaré's homology sphere is a closed 3- manifold with the same homology as the 3-sphere but with a fundamental group which is non-trivial. In his series of papers on Analysis situs (1892 - 1904) Poincaré introduced the fundamental group and studied Betti-numbers and torsion coefficients. He asked himself the question how strong these ...

Being a spherical 3-manifold, it is the only homology 3-sphere (besides the 3-sphere itself) with a finite fundamental group. Its fundamental group is known as the binary icosahedral group and has order 120.
