Journal ArticleDOI
On the Fibonacci k-numbers
Sergio Falcon,Ángel Plaza +1 more
TL;DR: In this paper, the authors introduced a general kth Fibonacci sequence that generalizes, between others, both the classic FIFO sequence and the Pell sequence, by studying the recursive application of two geometrical transformations used in the well-known 4TLE partition.
Journal ArticleDOI
The k-Fibonacci sequence and the Pascal 2-triangle
Sergio Falcon,Ángel Plaza +1 more
TL;DR: In this paper, the general k-Fibonacci sequence was found by studying the recursive application of two geometrical transformations used in the well-known 4-triangle longest-edge partition.
Journal ArticleDOI
On k-Fibonacci sequences and polynomials and their derivatives
Sergio Falcon,Ángel Plaza +1 more
TL;DR: In this paper, the derivatives of k-Fibonacci polynomials are presented in the form of convolution of KF-FBNs and their properties admit a straightforward proof.
Journal ArticleDOI
Local refinement of simplicial grids based on the skeleton
Ángel Plaza,Graham F. Carey +1 more
TL;DR: A novel approach to the development of a class of local simplicial refinement strategies and the numerical results obtained appear to confirm that the measure of degeneracy of subtetrahedra is bounded, and converges asymptotically to a fixed value when the refinement proceeds.
Journal ArticleDOI
On k-Fibonacci numbers of arithmetic indexes
Sergio Falcon,Ángel Plaza +1 more
TL;DR: The sums of k-Fibonacci numbers with indexes in an arithmetic sequence, say an þ r for fixed integers a and r, are studied to give in a straightforward way several formulas for the sums of such numbers.
