On the Fibonacci k-numbers

S Falcón, Á Plaza - Chaos, Solitons & Fractals, 2007 - Elsevier
We introduce a general Fibonacci sequence that generalizes, between others, both the
classic Fibonacci sequence and the Pell sequence. These general kth Fibonacci numbers …

The k-Fibonacci sequence and the Pascal 2-triangle

S Falcon, Á Plaza - Chaos, Solitons & Fractals, 2007 - Elsevier
The general k-Fibonacci sequence {Fk, n} n= 0∞ were found by studying the recursive
application of two geometrical transformations used in the well-known 4-triangle longest …

Novel theorems for the frame bundle endowed with metallic structures on an almost contact metric manifold

MNI Khan - Chaos, Solitons & Fractals, 2021 - Elsevier
It has been found that an almost complex structure of a contact metric manifold on frame
bundle (FM, g D, J) is an almost Hermitian manifold. The derivative and coderivative of the …

Novel theorems for metallic structures on the frame bundle of the second order

MNI Khan - Filomat, 2022 - doiserbia.nb.rs
It is well known that 'an almost complex structure'J that is J2=− I on the manifold M is called
'an almost Hermitian manifold'(M, J, G) if G (JX, JY)= G (X, Y) and proved that (F2M, JD, GD) …

K-Narayana sequence self-Similarity. flip graph views of k-Narayana self-Similarity

E Özkan, B Kuloǧlu, JF Peters - Chaos, Solitons & Fractals, 2021 - Elsevier
This paper introduces self-similarity inherent in planar Milich-Jennings centered flip graphs
derived from the Narayana sequence. We show that self-similarity found in a Narayana …
