In mathematics, a field is pseudo algebraically closed if it satisfies certain properties which hold for any algebraically closed field. The concept was introduced by James Ax in 1967.〔Fried & Jarden (2008) p.218〕 ==Formulation== A field ''K'' is pseudo algebraically closed (usually abbreviated by PAC〔) if one of the following equivalent conditions holds: *Each absolutely irreducible variety defined over has a -rational point. *For each absolutely irreducible polynomial with and for each nonzero there exists such that and . *Each absolutely irreducible polynomial has infinitely many -rational points. *If is a finitely generated integral domain over with quotient field which is regular over , then there exist a homomorphism such that for each 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 algebraically closed field」の詳細全文を読む スポンサード リンク
