Fibonacci words in hyperbolic Pascal triangles

The hyperbolic Pascal triangle HPT_4,q (q ≥ 5) 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 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 HPT_4,q imply a graph structure between the finite Fibonacci words.
