Extended Fibonacci numbers and polynomials with probability applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 50, Page 2681-2693, 2004., 2004
The extended Fibonacci sequence of numbers and polynomials is introduced and studied. The generating function, recurrence relations, an expansion in terms of multinomial coefficients, and several properties of the extended Fibonacci numbers and ...

The number of distinct adjacent pairs in geometrically distributed words: a probabilistic and combinatorial analysis [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
The analysis of strings of $n$ random variables with geometric distribution has recently attracted renewed interest: Archibald et al. consider the number of distinct adjacent pairs in geometrically distributed words.

A note on limits of sequences of binary trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
We discuss a notion of convergence for binary trees that is based on subtree sizes. In analogy to recent developments in the theory of graphs, posets and permutations we investigate some general aspects of the topology, such as a characterization of the ...

Bounded affine permutations I. Pattern avoidance and enumeration [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2021
We introduce a new boundedness condition for affine permutations, motivated by the fruitful concept of periodic boundary conditions in statistical physics. We study pattern avoidance in bounded affine permutations.

Evaluation of the effects of chlorhexidine digluconate with and without cBD103 or cCath against multidrug‐resistant clinical isolates of Staphylococcus pseudintermedius

open access: yesVeterinary Dermatology, Volume 33, Issue 1, Page 17-e6, February 2022., 2022
Background – Because of the increased incidence of multidrug‐resistant (MDR) bacteria, the use of disinfectants over antibiotics has been encouraged. However, the interactions between disinfectants and host local immunity are poorly understood. Objective – To assess the effects of chlorhexidine digluconate (Chx), with and without selected host defence ...

On an alternative sequence comparison statistic of Steele [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
The purpose of this paper is to study a statistic that is used to compare the similarity between two strings, which is first introduced by Michael Steele in 1982.

Cosine polynomials with few zeros

open access: yesBulletin of the London Mathematical Society, Volume 53, Issue 3, Page 877-892, June 2021., 2021
Abstract In a celebrated paper, Borwein, Erdélyi, Ferguson and Lockhart constructed cosine polynomials of the form fA(x)=∑a∈Acos(ax),with A⊆N, |A|=n and as few as n5/6+o(1) zeros in [0,2π], thereby disproving an old conjecture of Littlewood. Here we give a sharp analysis of their constructions and, as a result, prove that there exist examples with as ...

Expected size of a tree in the fixed point forest [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
We study the local limit of the fixed-point forest, a tree structure associated to a simple sorting algorithm on permutations. This local limit can be viewed as an infinite random tree that can be constructed from a Poisson point process configuration on

EXPECTED MEAN WIDTH OF THE RANDOMIZED INTEGER CONVEX HULL

open access: yesMathematika, Volume 67, Issue 2, Page 422-433, April 2021., 2021
Abstract Let K⊂Rd be a convex body, and assume that L is a randomly rotated and shifted integer lattice. Let KL be the convex hull of the (random) points K∩L. The mean width W(KL) of KL is investigated. The asymptotic order of the mean width difference W(λK)−W((λK)L) is maximized by the order obtained by polytopes and minimized by the order for smooth ...
