A complete quasinormed vector space is called a quasi-Banach space. A quasinormed space $(A,\; \backslash |\; \backslash cdot\; \backslash |)$ is called a quasinormed algebra if the vector space ''A'' is an algebra and there is a constant ''K'' > 0 such that :$\backslash |xy\backslash |\; \backslash leq\; K\; \backslash |x\backslash |\; \backslash cdot\; \backslash |y\backslash |$ for all $x,\; y\; \backslash in\; A$. A complete quasinormed algebra is called a quasi-Banach algebra. 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「Quasinorm」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.
