書籍描述

內容簡介

《群與對稱》講述瞭 numbers measure size, groups measure symmetry. the first statement comes as no surprise; after all, that is what numbers are for. the second will be exploited here in an attempt to introduce the vocabulary and some of the highlights of elementary group theory.
a word about content and style seems appropriate. in this volume, the emphasis is on examples throughout, with a weighting towards the symmetry groups of solids and patterns. almost all the topics have been chosen so as to show groups in their most natural role, acting on (or permuting) the members ora set, whether it be the diagonals of a cube, the edges of a tree, or even some collection of subgroups of the given group. the material is divided into twenty-eight short chapters, each of which introduces a new result or idea.a glance at the contents will show that most of the mainstays of a first course arc here. the theorems of lagrange, cauchy, and sylow all have a chapter to themselves, as do the classifcation of finitely generated abelian groups, the enumeration of the finite rotation groups and the plane crystallographic groups, and the nielsen-schreier theorem.

一般指圖形和形態被點、綫或平麵區分為相等的部分而言。在生物形態上主要的對稱分為下列各種:(1)輻射對稱:與身體主軸成直角且互為等角的幾個軸(輻射軸)均相等,如果通過輻射軸把含有主軸的身體切開時,則常可把身體分為顯鏡像關係的兩個部分。例如海星可見有五個輻射軸。另外在高等植物的莖和花等,也常具有輻射對稱的結構;
