Random permutations and their discrepancy process [PDF]
Discrete Mathematics & Theoretical Computer Science, 2007 Let $\sigma$ be a random permutation chosen uniformly over the symmetric group $\mathfrak{S}_n$. We study a new "process-valued" statistic of $\sigma$, which appears in the domain of computational biology to construct tests of similarity between ordered ...

On the deformed Besov-Hankel spaces [PDF]
Opuscula Mathematica, 2020 In this paper we introduce function spaces denoted by \(BH_{\kappa,\beta}^{p,r}\) (\(0\lt\beta\lt 1\), \(1\leq p, r \leq +\infty\)) as subspaces of \(L^p\) that we call deformed Besov-Hankel spaces.

CALCULATING BEDLOAD TRANSPORT IN RIVERS: CONCEPTS, CALCULUS ROUTINES AND APPLICATION
Revista Brasileira de Geomorfologia, 2017 Rivers are immensely important to human activities such as water supply, navigation, energy generation, and agriculture. They are also an important morphodynamic agent of erosion, transport and deposition.

A general 2-part Erdȍs-Ko-Rado theorem [PDF]
Opuscula Mathematica, 2017 A two-part extension of the famous Erdȍs-Ko-Rado Theorem is proved. The underlying set is partitioned into \(X_1\) and \(X_2\). Some positive integers \(k_i\), \(\ell_i\) (\(1\leq i\leq m\)) are given.

Zero-sum partitions of Abelian groups of order $2^n$ [PDF]
Discrete Mathematics & Theoretical Computer Science, 2023 The following problem has been known since the 80's. Let $\Gamma$ be an Abelian group of order $m$ (denoted $|\Gamma|=m$), and let $t$ and $m_i$, $1 \leq i \leq t$, be positive integers such that $\sum_{i=1}^t m_i=m-1$.

$p$-groups with a small number of character degrees and their normal subgroups [PDF]
International Journal of Group TheoryIf $G$ be a finite $p$-group and $\chi$ is a non-linear irreducible character of $G$, then $\chi(1)\leq |G/Z(G)|^{\frac{1}{2}}$. In \cite{fernandez2001groups}, Fern\'{a}ndez-Alcober and Moret\'{o} obtained the relation between the character degree set of

On the 2-adic order of Stirling numbers of the second kind and their differences [PDF]
Discrete Mathematics & Theoretical Computer Science, 2009 Let $n$ and $k$ be positive integers, $d(k)$ and $\nu_2(k)$ denote the number of ones in the binary representation of $k$ and the highest power of two dividing $k$, respectively.

Riesz transforms on graphs for $1 \leq p \leq 2$
MATHEMATICA SCANDINAVICA, 2000 Let \(\Gamma\) be a connected infinite, locally unifomly finite graph having the doubling property and endowed with a reversible Markov kernel \(p\). Let \(\nabla\) be a discrete gradient, \(Pf(x)=\sum_{y\in \Gamma}^{}p(x,y)f(y)\) and \(I\) be the identity operator.

Continuity in a parameter of solutions to generic boundary-value problems
Electronic Journal of Qualitative Theory of Differential Equations, 2016 We introduce the most general class of linear boundary-value problems for systems of first-order ordinary differential equations whose solutions belong to the complex Hölder space $C^{n+1,\alpha}$, with $0\leq n\in\mathbb{Z}$ and $0\leq\alpha\leq 1$. The

The norming sets of multilinear forms on a certain normed space $\mathbb{R}^n$
Математичні СтудіїLet $n, m\in \mathbb{N}, n, m\geq 2$ and $E$ a Banach space. An element $(x_1, \ldots, x_n)\in E^n$ is called a~norming point of $T\in {\mathcal L}(^n E)$ if $\|x_1\|=\cdots=\|x_n\|=1$ and $|T(x_1, \ldots, x_n)|=\|T\|,$ where ${\mathcal L}(^n E ...
