Effective Computation of Generalized Abelian Complexity for Pisot Type Substitutive Sequences

Generalized abelian equivalence compares words by their factors up to a certain bounded length. The associated complexity function counts the equivalence classes for factors of a given size of an infinite sequence. How practical is this notion?

Tribonacci-like sequences and generalized Pascal's pyramids

International Journal of Mathematical Education in Science and Technology, 2014
A well-known result of Feinberg and Shannon states that the tribonacci sequence can be detected by the so-called Pascal's pyramid. Here we will show that any tribonacci-like sequence can be obtained by the diagonals of the Feinberg's triangle associated to a suitable generalized Pascal's pyramid.

Using Matrix Techniques to Establish Properties of a Generalized Tribonacci Sequence

, 1991
We consider the generalized Tribonacci Sequence, {V n }, defined as follows: $$ {V_n} = r{V_{n - 1}} + s{V_{n - 2}} + t{V_{n - 3}} (n \geqslant 3), $$ (1) where Vo, V1, V2 are arbitrary integers and r, s, t, are non-zero integers.
