Almost Repdigit k-Fibonacci Numbers with an Application of k-Generalized Fibonacci Sequences

open access: yesMathematics, 2023
In this paper, we define the notion of almost repdigit as a positive integer whose digits are all equal except for at most one digit, and we search all terms of the k-generalized Fibonacci sequence which are almost repdigits. In particular, we find all k-

Revisiting Fisher's n‐D statistical vision: From algebraic abstraction to modern visualization

open access: yesCanadian Journal of Statistics, Volume 54, Issue 3, September 2026.
Abstract We revisit early foundational results in mathematical statistics derived by Ronald A. Fisher. They involve sampling distributions of statistics calculated from independent and identically distributed Normal observations, namely the root mean square deviation; the mean absolute deviation, conditional on already knowing the value of the root ...

Diophantine equations with Lucas and Fibonacci number coefficients [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Fibonacci and Lucas numbers are special number sequences that have been the subject of many studies throughout history due to the relations they provide.

Structure and Computation

open access: yesNoûs, Volume 60, Issue 3, Page 593-605, September 2026.
ABSTRACT It is a truism of mathematics that differences between isomorphic number systems are irrelevant to arithmetic. This truism is deeply rooted in the modern axiomatic method and underlies most strands of arithmetical structuralism, the view that arithmetic is about some abstract number structure.

On Doubled and Quadrupled Fibonacci Type Sequences

open access: yesAnnales Mathematicae Silesianae
In this paper we study a family of doubled and quadrupled Fibonacci type sequences obtained by distance generalization of Fibonacci sequence. In particular we obtain doubled Fibonacci sequence, doubled and quadrupled Padovan sequence and quadrupled ...

On Matrix‐Based Cryptography Using Matrix Norm and Special Integer Sequences

open access: yesMathematische Nachrichten, Volume 299, Issue 8, Page 2087-2102, August 2026.
ABSTRACT In this paper, a novel matrix‐based encryption approach based on the Affine Hill cipher is presented. The key matrix is constructed using the Narayana integer sequence, and the Frobenius norm of the key matrix is used as a scaling factor in the key construction.

Sums of certain products of fibonacci & Lucas numbers-part III [PDF]

open access: yes, 2017
For the Fibonacci numbers, the summation formula σnk=1 Fk2=FnFn+1is well-known. Its charm lies in the fact that the right side is a product of terms from the Fibonacci sequence.

Elliptic curve and k-Fibonacci-like sequence

open access: yes, 2023
In this paper, we will introduce a modified k-Fibonacci-like sequence defined on an elliptic curve and prove Binet’s formula for this sequence.

Embodied Responses to Harmony and (Poly)Rhythm: An Integrated Ratio‐Based Perception‐Action Framework

open access: yesAnnals of the New York Academy of Sciences, Volume 1562, Issue 1, August 2026.
Harmony and rhythm perception are often studied separately, yet both reveal a shared sensitivity to low‐order integer ratios. In harmony, intervals like the octave (2:1) and fifth (3:2) predict consonance and ease of encoding. In rhythm, patterns with simple ratios (e.g., 2:1, 3:2) are easier to perceive, reproduce, and remember.

What does a modified-Fibonacci dose-escalation actually correspond to?

open access: yesBMC Medical Research Methodology, 2012
Background In most phase I oncology trials, it is often stated that the dose increments follow a “modified-Fibonacci sequence”. This term, however, is vague.
