On the constant coefficients of a certain recurrence relation: A simple proof
Milica Anđelić, Carlos M. da Fonseca · Heliyon · 2021
In this note, we provide a short proof for the explicit formulas of the coefficients of a particular 3-term recurrence relation derived from a k -periodic recurrence. Any of the recurrences can be naturally interpreted in terms of determinants of Hessenberg matrices families.
