Complexity of Linear Subsequences of Fibonacci-Automatic Sequences
This work addresses theoretical computer science problems related to automata and number theory, with incremental contributions to state complexity analysis.
The paper constructs automata using Fibonacci representation to recognize basic arithmetic relations and operations on Fibonacci-automatic sequences, analyzing their state complexity and improving a bound from prior work.
We construct automata with input(s) in Fibonacci representation (also known as Zeckendorf representation) recognizing some basic arithmetic relations and study their number of states. We also consider some basic operations on Fibonacci-automatic sequences and discuss their state complexity. Furthermore, as a consequence of our results, we improve a bound in a recent paper of Bosma and Don. We also discuss the state complexity and runtime complexity of using a reasonable interpretation of Büchi arithmetic to actually construct some of the studied automata recognizing relations.
