This equation has the following structure : In quantum electrodynamics this equation takes the form : It was discovered independently by Curtis Callan〔C. G. Callan, Jr., ''Broken Scale Invariance in Scalar Field Theory'', Phys. Rev. D 2, 1541–1547 (1970). (APS )〕 and Kurt Symanzik〔K. Symanzik, ''Small Distance Behaviour in Field Theory and Power Counting'', Commun. math. Phys. 18, 227 (1970). (SpringerLink )〕〔K. Symanzik, ''Small-Distance-Behaviour Analysis and Wilson Expansions'', Commun. math. Phys. 23, 49 (1971). (SpringerLink )〕 in 1970. Later it was used to understand asymptotic freedom. This equation arises in the framework of renormalization group. It is possible to treat the equation using perturbation theory. ==See also== *Exact renormalization group equation *Beta function 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「Callan–Symanzik equation」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.
