书籍介绍

《对称和凝聚态物理学中的计算方法》内容简介：The main emphasis， throughout this book， is on exposing the conceptual building blocksof this mathematical theory of symmetry． Consequently， we frequently skip over long detailed mathematical proofs which can be found in a multitude of textbooks． Instead， we point the reader to references where such proofs are clearly presented． Moreover， in contrast to previous texts on the subject， the different aspects of group theory are presented wherever they are needed rather than being lumped into one single expose． This has the merit of associating a certain aspect of the theory with a tangible physical attribute． Thus， for example， we defer the introduction of cosets and invariant subgroups till we discuss spacegroups， where they find immediate application．
