Abstract

The canonical low-to-high Zeckendorf normalization is non-subsequential with exact prefix-destruction index Delta(n)=n. The Berstel transducer is proved minimal with exact state complexity 10 via kernel separation.

Keywords: Zeckendorf numeration, transducer theory, subsequential functions, Fibonacci addition, state complexity
