In mathematics, a pseudo-monotone operator from a reflexive Banach space into its continuous dual space is one that is, in some sense, almost as well-behaved as a monotone operator. Many problems in the calculus of variations can be expressed using operators that are pseudo-monotone, and pseudo-monotonicity in turn implies the existence of solutions to these problems. ==Definition== Let (''X'', || ||) be a reflexive Banach space. A map ''T'' : ''X'' → ''X''∗ from ''X'' into its continuous dual space ''X''∗ is said to be pseudo-monotone if ''T'' is a bounded operator (not necessarily continuous) and if whenever : (i.e. ''u''''j'' converges weakly to ''u'') and : it follows that, for all ''v'' ∈ ''X'', : 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「Pseudo-monotone operator」の詳細全文を読む スポンサード リンク
