我们引入了一个无关上下文的语法G = s + d, d s来生成斐波那契和卢卡斯序列。应用语法G,给出了Binet公式的语法证明。此外,我们使用语法G提供了一种统一的方法来证明Hoggatt, Carlitz和Church给出的关于Fibonacci和Lucas数的几个二项式卷积。同时,我们也得到了一些新的二项卷积。
We introduce a context-free grammar G = s ⟶ s + d , d ⟶ s to generate Fibonacci and Lucas sequences. By applying the grammar G , we give a grammatical proof of the Binet formula. Besides, we use the grammar G to provide a unified approach to prove several binomial convolutions about Fibonacci and Lucas numbers, which were given by Hoggatt, Carlitz, and Church. Meanwhile, we also obtain some new binomial convolutions.
