From the representation theory point of view, a primary is the lowest dimension operator in a given representation of the conformal algebra. All other operators in a representation are called ''descendants''; they can be obtained by acting on the primary with the raising generators. ==History of the concept== Primary fields in a ''D''-dimensional conformal field theory were introduced in 1969 by Mack and Salam where they were called ''interpolating fields''. They were then studied by Ferrara, Gatto, and Grillo who called them ''irreducible conformal tensors'', and by Mack who called them ''lowest weights''. Polyakov used an equivalent definition as fields which cannot be represented as derivatives of other fields. The modern terms ''primary fields'' and ''descendants'' were introduced by Belavin, Polyakov and Zamolodchikov in the context of two-dimensional conformal field theories. This terminology is now used both for ''D''=2 and ''D''>2. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Primary field」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
