n型序列a^n + b^n

Integer Sequences of the Form a^n + b^n

Abdulrahman Ali Abdulaziz

摘要:

在本文中,我们找到了所有的整数序列的形式a^n + b^n,其中a和b是复数,n是一个非负整数。证明了当p和q为整数时,二次方程z^2 -pz-q = 0的根与形式为a^n + b^n的整数序列之间存在对应.此外,我们将证明不存在形式为a^n-b ^n的整数序列。最后,我们利用a和b的特殊值得到了一系列涉及Lucas数和斐波那契数的公式。

英文摘要:

In this paper, we find all integer sequences of the form a^n + b^n, where a and b are complex numbers and n is a nonnegative integer. We prove that if p and q are integers, then there is a correspondence between the roots of the quadratic equation z^2 - pz - q = 0 and integer sequences of the form a^n + b^n. In addition, we will show that there are no integer sequences of the form a^n - b^n. Finally, we use special values of a and b to obtain a range of formulas involving Lucas and Fibonacci numbers.
