The Schoenflies (or Schönflies) notation, named after the German mathematician Arthur Moritz Schoenflies, is a notation primarily used to specify point groups in three dimensions. Because a point group alone is completely adequate to describe the symmetry of a molecule , the notation is often sufficient and commonly used for spectroscopy .
Arthur Moritz Schoenflies (German: [ˈʃøːnfliːs]; 17 April 1853 – 27 May 1928), sometimes written as Schönflies, was a German mathematician, known for his contributions to the application of group theory to crystallography, and for work in topology.
There are 3 types of dihedral symmetry in three dimensions, each shown below in 3 notations: Schönflies notation, Coxeter notation, and orbifold notation. Chiral. D n, [n,2] +, (22n) of order 2n – dihedral symmetry or para-n-gonal group (abstract group: Dih n).
Walter Bendix Schönflies Benjamin (/ ˈ b ɛ n j ə m ɪ n / BEN-yə-min; German: [ˈvaltɐ ˈbɛnjamiːn] ⓘ; [7] 15 July 1892 – 26 September 1940 [8]) was a German-Jewish philosopher, cultural critic, media theorist, and essayist.
However, one should remember that, unlike Schoenflies notation, the direction of a plane in a Hermann–Mauguin symbol is defined as the direction perpendicular to the plane, and in the D 3d group all mirror planes are perpendicular to 2-fold axes, so they should be written in the same position as 2 / m .
The original formulation of the Schoenflies problem states that not only does every simple closed curve in the plane separate the plane into two regions, one (the "inside") bounded and the other (the "outside") unbounded; but also that these two regions are homeomorphic to the inside and outside of a standard circle in the plane.
