Group theory is the branch of mathematics that studies symmetry, found in crystals, art, architecture, music and many other contexts. But its beauty is lost on students when it is taught in a technical style that is difficult to understand. Visual Group Theory assumes only a high school mathematics background and covers a typical undergraduate course in group theory from a thor...(展开全部)

During the last 40 years the theory of finite groups has developed dramatically. The finite simple groups have been classified and are becoming better understood. Tools exist to reduce many questions about arbitrary finite groups to similar questions about simple groups. Since the classification there have been numerous applications of this theory in other branches of mathemati...(展开全部)

Social scientists have long recognized that solidarity is essential for such phenomena as social order, class, and ethnic consciousness, and the provision of collective goods. In presenting a new general theory of group solidarity, Michael Hechter here contends that it is indeed possible to build a theory of solidarity based on the action of rational individuals and in doing so...(展开全部)
