Sury和McLaughlin恒等式的组合化,一般线性递归的统一方法
Combinatorialization of Sury and McLaughlin identities, general linear recurrences in a unified approach
摘要:
在这篇文章中,我们提供了一些最近的身份由于苏里和麦克劳克林的组合证明。证明了一般的常系数线性递推式的解可以解释为矩阵的行列式。此外,我们还得到了Fibonacci数和Lucas数的行列式表达式。本文用纯组合的方法证明了Fibonacci数和Lucas数的Bevel公式,并在证明过程中发现了一个行列式恒等式,我们认为这是一个新的恒等式。
英文摘要:
In this article we provide with combinatorial proofs of some recent identities due to Sury and McLaughlin. We show that, the solution of a general linear recurrence with constant coefficients can be interpreted as a determinant of a matrix. Also, we derive a determinantal expression of Fibonacci and Lucas numbers. We prove Binets formula for Fibonacci and Lucas numbers in a purely combinatorial way and in course of doing so, we find a determinantal identity, which we think to be new.
