In functional analysis, a branch of mathematics, a Beppo-Levi space, named after Beppo Levi, is a certain space of generalized functions. In the following, is the space of distributions, is the space of tempered distributions in , the differentiation operator with a multi-index, and is the Fourier transform of . The Beppo-Levi space is : where denotes the Sobolev semi-norm. An alternative definition is as follows: let such that : and define: : Then is the Beppo-Levi space. ==References== * Wendland, Holger (2005), ''Scattered Data Approximation'', Cambridge University Press. * Rémi Arcangéli; María Cruz López de Silanes; Juan José Torrens (2007), "An extension of a bound for functions in Sobolev spaces, with applications to (m,s)-spline interpolation and smoothing" ''Numerische Mathematik'' * Rémi Arcangéli; María Cruz López de Silanes; Juan José Torrens (2009), "Estimates for functions in Sobolev spaces defined on unbounded domains" ''Journal of Approximation Theory'' 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「Beppo-Levi space」の詳細全文を読む スポンサード リンク
