Non-standard binary representations and the Stern sequence

Combinatorics 2023-08-16 v1 Number Theory

Abstract

We show that the number of short binary signed-digit representations of an integer nn is equal to the nn-th term in the Stern sequence. Various proofs are provided, including direct, bijective, and generating function proofs. We also show that this result can be derived from recent work of Monroe on binary signed-digit representations of a fixed length.
