A complex number is said to be hypertranscendental if it is not the value at an algebraic point of a function which is the solution of an algebraic differential equation with coefficients in Z() and with algebraic initial conditions. The term was introduced by D. D. Morduhai-Boltovskoi in "Hypertranscendental numbers and hypertranscendental functions" (1949). The term is related to transcendental numbers, which are numbers which are not a solution of a non-zero polynomial equation with rational coefficients. The number ''e'' is transcendental but not hypertranscendental, as it can be generated from the solution to the differential equation . Any hypertranscendental number is also a transcendental number. ==See also== * Hypertranscendental function 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「Hypertranscendental number」の詳細全文を読む スポンサード リンク
