Chromatic zeros and generalized Fibonacci numbers

Alikhani Saeid, Peng Yee-Hock

In this article we consider the problem whether generalized Fibonacci constants can be zeros of chromatic polynomials. We prove that all 2n-anacci numbers and all their natural powers cannot be zeros of any chromatic polynomial. Also we investigate (2n + 1)-anacci numbers as chromatic zeros.

Keywords: Chromatic Zero, Fibonacci Numbers, n-anacci constants
