Asymptotic formula - recurrence formula

Japanese: 漸近式 - ぜんきんしき(英語表記)recurrence formula
Asymptotic formula - recurrence formula
For a function f ( x ) defined in domain D and a boundary point a of D , if there exists a function g ( x ) such that g ( x ) is called the asymptotic formula of f ( x ) as x approaches a . Let us express this as f ( x ) ~ g ( x ). An example of this is Stirling's formula, which gives the asymptotic formula for the gamma function, when x → +∞. Asymptotic formulas are also sometimes used in relation to sequences. For a sequence { a n }, if there exists a sequence { b n } such that { a n } and { b n } are said to be asymptotically equal.

領域Dで定義された関数f(x)とDの境界点aに対して,となる関数g(x)が存在するとき,g(x)をxaに近づくときのf(x)の漸近式という。これをf(x)~g(x)と表すことにする。x→+∞のときのガンマ関数,の漸近式を与えるスターリングの公式,はこの例である。漸近式は数列に関しても使われることがある。数列{an}に対して,となる数列{bn}が存在するとき,{an}と{bn}は漸近的に等しいという。
