Mathematics 402A Final Solutions

Solution. Suppose that G is an abelian ,group, of order 8. By Lagrange’s theorem, the elements of G can have order 1, 2, 4, or 8. If G contains an ,element, of order 8, then G is cyclic, generated by that ,element,: G ˇC8. Suppose that G has no elements of order 8, but contains an ,element, x of order 4. Let H =f1;x;x2;x3g

Weyl group - Wikipedia

In mathematics, in particular the theory of Lie algebras, the ,Weyl group, of a root system Φ is a subgroup of the isometry ,group, of the root system.Specifically, it is the subgroup which is generated by reflections through the hyperplanes orthogonal to the roots, and as such is a finite reflection ,group,.Abstractly, Weyl groups are finite Coxeter groups, and are important examples of these.

Group Theory and Sage — Thematic Tutorials v9.2

Given an ,element, \(g \in G\), the “,centralizer,” of \(g\) is the set \(C(g) = \{h \in G \mid hgh^{-1} = g\}\), which is a subgroup of \(G\). A theorem tells us that the size of each conjugacy class is the order of the ,group, divided by the order of the ,centralizer of an element, of the class.
