In mathematics, the Tate curve is a curve defined over the ring of formal power series with integer coefficients. Over the open subscheme where ''q'' is invertible, the Tate curve is an elliptic curve. The Tate curve can also be defined for ''q'' as an element of a complete field of norm less than 1, in which case the formal power series converge. The Tate curve was introduced by in a 1959 manuscript originally titled "Rational Points on Elliptic Curves Over Complete Fields"; he did not publish his results until many years later, and his work first appeared in . ==Definition== The Tate curve is the projective plane curve over the ring Z of formal power series with integer coefficients given (in an affine open subset of the projective plane) by the equation : where : : are power series with integer coefficients.〔Manin & Panchishkin (2007) p.220〕 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「Tate curve」の詳細全文を読む スポンサード リンク
