Seminar Room 1, Newton Institute


We prove that all natural power of golden ratio, cannot be a root of any chromatic polynomial.

We also consider generalized Fibonacci sequences and prove that all 2n-anacci constants and all natural powers of them cannot be root of any chromatic polynomial. Finally, we introduce new numbers related to n-annaci numbers and ask a question similar to Beraha question.
