This text provides an introduction to group theory with an emphasis on clear examples. The authors present groups as naturally occurring structures arising from symmetry in geometrical figures and other mathematical objects. Written in a 'user-friendly' style, where new ideas are always motivated before being fully introduced, the text will help readers to gain confidence and skill in handling group theory notation before progressing on to applying it in complex situations. An ideal companion to any first or second year course on the topic.
very elementary introduction to group theory. I got it for self-learning basic concepts of group theory and I found it very helpful. The exercises are well picked: consolidating the concepts the last section and pave roads for the up coming development - I recommend spend some time doing all of them. You may be able to get by 3 chapters without doing any problems but eventually you're messing something up unless you're genius. This book requires little math background, but knowing some basic combinatorics will help you do the problems fast. Group theory is a fascinating subject. I can't wait to learn more about it. In an ecstatic nonmathematician way of understanding, groups, in a certain sense, gives structure to things conversely the structure within a group is better understood or proved through its action on things. Different numbers also accomandate different structures.
