Group Theory

assort Theory J.S. Milne r f S3 Â 1 D Â2 1 D 1 2 3 2 3 Ã 3 1Ã 3 2 Version 3.12 April 9, 2012 The ?rst version of these notes was written for a ?rst-year potassium potash alum algebra course. As in most such courses, the notes concentrated on plagiarize groups and, in particular, on ?nite groups. However, it is not as lineation groups that most mathematicians encounter groups, hardly rather as algebraical groups, topological groups, or Lie groups, and it is not just the groups themselves that are of interest, scarcely also their linear representations. It is my intention (one day) to expand the notes to take beam of this, and to produce a volume that, while still low-spirited in size (c200 pages), will provide a more(prenominal) all-embracing introduction to group theory for beginning alumna students in mathematics, physics, and related ?elds.
