Title: Fibonacci words in hyperbolic Pascal triangles,
Abstract: The hyperbolic Pascal triangle ${\cal HPT}_{4,q}$ $(q\ge5)$ is a new
mathematical construction, which is a geometrical generalization of Pascal's
arithmetical triangle. In the present study we show that a natural pattern of
rows of ${\cal HPT}_{4,5}$ is almost the same as the sequence consisting of
every second term of the well-known Fibonacci words. Further, we give a
generalization of the Fibonacci words using the hyperbolic Pascal triangles.
The geometrical properties of a ${\cal HPT}_{4,q}$ imply a graph structure
between the finite Fibonacci words.
