Diophantine

释义 Definition

丢番图的;与“只求整数(或有理数)解的方程/问题”有关的。
常见于数学语境,如 Diophantine equation(丢番图方程)Diophantine approximation(丢番图逼近)

发音 Pronunciation

/dafn.tan/

例句 Examples

A Diophantine equation asks for integer solutions.
丢番图方程要求寻找整数解。

The proof reduces the problem to a Diophantine condition on the coefficients, so only certain integer values are possible.
该证明把问题化简为对系数的一个丢番图条件,因此只有某些整数取值才可能成立。

词源 Etymology

Diophantine 来自古希腊数学家 Diophantus of Alexandria(亚历山大的丢番图) 的名字。丢番图因研究用代数方法处理整数解问题而闻名,后来与“整数解相关的方程与数论问题”逐渐用他的名字来命名。
