Grid classes and the Fibonacci dichotomy for restricted permutations
, 2006 We introduce and characterise grid classes, which are natural generalisations of other well-studied permutation classes. This characterisation allows us to give a new, short proof of the Fibonacci dichotomy: the number of permutations of length n in a ...

Another type of generalized fibonacci series
Semina: Ciências Exatas e Tecnológicas, 2004 The Fibonacci sequence, with many applications and occurrences in nature and arts is discussed in the present work. It is considered a generalization of the Fibonacci series by the introduction of a real coefficient in the recurrence relation.

Adaptive Fractional Hybrid Impedance Control of Rotary Series Elastic Actuator in Flat Terrains
Advanced Intelligent Systems, Volume 7, Issue 6, June 2025.This article presents an adaptive fractional hybrid impedance control (AFH‐IC) approach for rotary series elastic actuators operating on flat terrains. The proposed method integrates fractional‐order control, adaptive fuzzy logic, and particle swarm optimization to enhance torque tracking accuracy and robustness.

Fibonacci and Telephone Numbers in Extremal Trees
Discussiones Mathematicae Graph Theory, 2018 In this paper we shall show applications of the Fibonacci numbers in edge-coloured trees. In particular we determine the successive extremal graphs in the class of trees with respect to the number of (A, 2B)-edge colourings.

Spherical GTM: A New Proposition for Visualization of Chemical Data
Molecular Informatics, Volume 44, Issue 5-6, June 2025.The Spherical Generative Topographic Mapping method extends the Generative Topographic Mapping method to a spherical manifold to address known nonflat topology issues. The mathematical formalism of this new approach is described, and its ability to visualize in 2D electron density patterns and a tangible chemical library is showcased.

A note on Fibonacci matrices of even degree
International Journal of Mathematics and Mathematical Sciences, 2001 This paper presents a construction of m-by-m irreducible Fibonacci matrices for any even m. The proposed technique relies on matrix representations of algebraic number fields which are an extension of the golden section field.

Fibonacci numbers: A population dynamics perspective
Heliyon, 2019 Fibonacci numbers or Fibonacci sequence is among the most popular numbers or sequence in Mathematics. In this paper, we discuss the sequence in a population dynamics perspective. We discuss the early development of the sequence and interpret the sequence
