An equivalent definition is that ''A'' is an algebra in ''C'' over the little ''n''-disks operad. == Examples == * An $\backslash mathcal\_n$-algebra in vector spaces over a field is a unital associative algebra if ''n''=1, and a unital commutative associative algebra if ''n''≥2. * An $\backslash mathcal\_n$-algebra in categories is a monoidal category if ''n''=1, a braided monoidal category if ''n''=2, and a symmetric monoidal category if ''n''≥3. * If Λ is a commutative ring, then $X\; \backslash mapsto\; C\_$ *(\Omega^n X; \Lambda) defines an $\backslash mathcal\_n$-algebra in the infinity category of chain complexes of $\backslash Lambda$-modules. 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「En-ring」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.
