Representation of solutions of eight systems of difference equations via generalized Padovan sequences [PDF]
, 2021 WOS:000692199000020We indicate that the systems of difference equations {formula presented} where the sequences pn, qn, rn, sn are some of the sequences xn and yn, f: Df → ℝ is a “1 – 1” continuous function on its domain Df ⊆ ℝ, initial values x−j, y−j ...

Restricted 123-avoiding Baxter permutations and the Padovan numbers [PDF]
, 2007 Baxter studied a particular class of permutations by considering fixed points of the composite of commuting functions. This class is called Baxter permutations.

Common terms of k-Pell numbers and Padovan or Perrin numbers
Arabian Journal of Mathematics, 2022 AbstractLet $$k\ge 2$$ k ≥ 2 . A generalization of the well-known Pell sequence is the k-Pell sequence. For this sequence, the first k terms are $$0,\ldots ,0,1$$ 0 ,

Journal of Phycology, Volume 62, Issue 2, Page 412-426, April 2026.Abstract The distribution and connectivity of species around the globe are changing at a rapid pace. Increasing sea temperatures are a driving factor of changes in temperate macroalgal distributions. Southeast Australia is considered a global ocean‐warming hotspot, where macroalgal populations are predicted to decline significantly by 2100.

Padovan and Perrin numbers as products of two generalized Lucas numbers
Archivum Mathematicum, 2023 Let \(P_m\) and \(E_m\) be the \(m\)th Padovan and Perrin numbers, respectively. Let \(r,s\in \mathbb{Z}\) with \(r\ge 1\) and \(s\in\{-1,1\}\), and let \(\{U_n\}_{n\ge 0}\) be the generalized Lucas sequence given by \[U_0=0,\quad U_1=1\quad\mbox{and}\quad U_{n+2}=rU_{n+1}+sU_n.\] In the paper under review, the authors give effective bounds for the ...

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.Methods to evaluate global radiation on the front side of the second row, accounting for direct shading and view factor masking effects, are developed. Moreover, the relationship between annual incident radiation on the second row and installation parameters such as tilt angle and space factor, is also discussed to maximize the regionally effective ...

Counting Maximal Distance-Independent Sets in Grid Graphs
Discussiones Mathematicae Graph Theory, 2013 Previous work on counting maximal independent sets for paths and certain 2-dimensional grids is extended in two directions: 3-dimensional grid graphs are included and, for some/any ℓ ∈ N, maximal distance-ℓ independent (or simply: maximal ℓ-independent ...

Dual Proximal Groups Concisely Representing Complex Hosoya Triangles
Advances in Mathematical Physics, Volume 2026, Issue 1, 2026.This paper introduces dual proximal groups (DPGs) that provide concise representation of complex Hosoya triangles (CHTs). An application is given in terms of the DPG representation of collections of Hosoya‐Hilbert circular triangles on modulated motion waveforms in sequences of video frames. MSC2020 Classification: 11B39,54E05,57S25.
