Group Theory
Symmetry has sung its siren song to Physicists since the beginning of time, or at least since before there were Physicists. Today the ideas of symmetry are incorporated into a subject with the less imaginative and suggestive name of Group Theory. This Chapter introduces many of the ideas of group theory that are important in the natural sciences. Natural philosophers in the past have come up wi...
متن کاملGroup Theory
The first version of these notes was written for a first-year graduate algebra course. As in most such courses, the notes concentrated on abstract groups and, in particular, on finite groups. However, it is not as abstract groups that most mathematicians encounter groups, but rather as algebraic groups, topological groups, or Lie groups, and it is not just the groups themselves that are of inte...
متن کاملGroup Theory
The notion of modular arithmetic is related to that of the remainder in Euclidean division. The operation of finding the remainder is sometimes referred to as the modulo operation, and denoted with ”mod” used as an infix operator. For example, the remainder of the division of 16 by 12 is denoted by 16 mod 12; as this remainder is 4, we have 16 mod 12 = 4. The congruence, indicated by ”≡” follow...
متن کاملFinite Group Theory
In the preface of Finite Group Theory the author, I. Martin Isaacs, states that his principal reason for writing the book was to expose students to the beauty of the subject. Finite group theory is indeed a subject which has both beautiful theory and beautiful examples. The simplicity and elegance of the group axioms have made group theory an almost universal choice as a starting point in the t...
متن کاملGeometric Group Theory Notes
Definition. Let Γ be a group. Take A ⊂ Γ to be any subset. The subgroup generated by A, denoted 〈A〉, is the smallest subgroup of Γ containing A. Equivalently, 〈A〉 is the intersection of all subgroups of Γ containing A. Equivalently, 〈A〉 = {a1 1 · · · an n | ai ∈ A, ǫi = ±1}, the set of finite products of elements of A ∪A−1. Notation. We will frequently use Γ to denote a group. If A is a set, A ...
