Web5 feb. 2011 · The Representations of Quantum Double of Dihedral Groups. Jingcheng Dong, Hui-xiang Chen. Published 5 February 2011. Mathematics. arXiv: Quantum … In mathematics, a dihedral group is the group of symmetries of a regular polygon, which includes rotations and reflections. Dihedral groups are among the simplest examples of finite groups, and they play an important role in group theory, geometry, and chemistry. The notation for the dihedral group differs … Meer weergeven Elements A regular polygon with $${\displaystyle n}$$ sides has $${\displaystyle 2n}$$ different symmetries: $${\displaystyle n}$$ rotational symmetries and $${\displaystyle n}$$ Meer weergeven The properties of the dihedral groups Dn with n ≥ 3 depend on whether n is even or odd. For example, the center of Dn consists only of the … Meer weergeven There are several important generalizations of the dihedral groups: • The infinite dihedral group is an infinite group with algebraic structure similar to the finite … Meer weergeven • Coordinate rotations and reflections • Cycle index of the dihedral group • Dicyclic group Meer weergeven An example of abstract group Dn, and a common way to visualize it, is the group of Euclidean plane isometries which keep the origin fixed. These groups form one of the two series of discrete point groups in two dimensions. Dn consists of n rotations of multiples of … Meer weergeven The automorphism group of Dn is isomorphic to the holomorph of $${\displaystyle \mathbb {Z} }$$/n$${\displaystyle \mathbb {Z} }$$, i.e., to Hol($${\displaystyle \mathbb {Z} }$$/n$${\displaystyle \mathbb {Z} }$$) = {ax + b (a, n) = 1} … Meer weergeven • Dihedral Group n of Order 2n by Shawn Dudzik, Wolfram Demonstrations Project. • Dihedral group at Groupprops Meer weergeven

Web1. The dihedral group D 2n of order 2nacts naturally on R2 by re ections and rotations. Find the matrices of two generating re ections s, tin the corresponding matrix representa-tion, and verify by computation the relation sts = tst (nfactors on each side). Hint: regard this as a complex matrix representation, and diagonalize the matrix of st. 2. WebThe indecomposable modular representations of certain groups with dihedral sylow subgroup P. W.
