Abstract We derive Mehler–Heine type asymptotic expansions for the Krawtchouk polynomials K n ( x ; p , N ) with n = O ( N ) and x = o ( N ) . These formulas provide good approximations for K n ( x ; p , N ) and determine the asymptotic limit of their zeros as n → ∞ .

Krawtchouk 多项式的 Mehler-Heine 型公式

摘要 我们推导出 Krawtchouk 多项式 K n ( x ; p , N ) 的 Mehler-Heine 型渐近展开式,其中 n = O ( N ) 且 x = o ( N ) 。这些公式为 K n ( x ; p , N ) 提供了很好的近似值,并将它们的零点的渐近极限确定为 n → ∞ 。
