Richard Klitzing
Dr. Richard Klitzing (born April 24th 1966) is a trained mathematician and trained physicist with a PhD in theoretical physics on the theory of quasicrystals that was granted by the Eberhard Karls University of Tübingen[1][2][3][4][5][6][7][8]. After a short time of teaching in higher degree schools he abandoned the profession, later returning sporadically as an external part-time lecturer at the cooperative State University of Heidenheim.
As a spare-time mathematician, he is responsible for the discovery of several scaliform and CRF polytopes. For instance, the first ever known scaliforms tuta, and prissi have been discovered by him. He also discovered several of the scaliform diminishings of polytopes; eg. oddimo, kadify, and codify.
Besides inventing the concept of scaliforms he also invented the segmentotopes[9] as a pedagogical means of easy to visualize monostratic polytopes, and researched on edge-facetings[10], e.g. he described first the chiral tetrahedral faceting quistet of sidtid. Further he expanded the concept of alternated faceting (aka snubbing) to alternations of higher-than-vertex elements[11], and he also expanded the notation of linearized Coxeter-Dynkin diagrams to include virtual nodes. He also contributed to the concept of tegum sums, initiated by Wout Gevaert.
He has his own website dedicated to polytopes [1], where he provides (currently) more than 9000 symmetry respecting incidence matrices for more than 4000 polytopes.
