摘要：

In 1953 Stancliff noted an interesting property of the Fibonacci number F-11 = 89. One has that 1/89 = 0/10 + 1/10(2) + 1/10(3) + 2/10(4) + 3/10(5) + 5/10(6) + ..., where in the numerators the elements of the Fibonacci sequence appear. We provide methods to determine similar identities in case of Lucas sequences. As an example we prove that 1/U-10 = 1/416020 = Sigma(infinity)(k=0) U-k/647(k+1), where U-0 = 0, U-1 = 1 and U-n = 4U(n-1) + Un-2, n >= 2.
