Pattern avoidance in partial permutations [PDF]
, 2011 Motivated by the concept of partial words, we introduce an analogous concept of partial permutations. A partial permutation of length n with k holes is a sequence of symbols $\pi = \pi_1\pi_2 ...

On an Extended Reverse Multidimensional Half-Discrete Hilbert-Type Inequality
AxiomsBy means of the weight functions, the idea of introduced parameters and the techniques of real analysis, we give a new reverse Hardy-type inequality and then obtain an extended reverse multidimensional half-discrete Hilbert-type inequality with the ...

The Enumeration of Sequences with Restrictions on their Partial Sums [PDF]
The Electronic Journal of Combinatorics, 2010 We examine sequences containing $p$ "$-t$"s and $pt+r$ "$+1$"s, where $p$, $t$, and $r$ are integers satisfying $p\ge0$, $t\ge 1$ and $pt+r\ge0$. We develop a rotation method to enumerate the number of sequences meeting additional requirements related to their partial sums.

A Generalized Sum-Difference Inequality and Applications to Partial Difference Equations
Advances in Difference Equations, 2008 We establish a general form of sum-difference inequality in two variables, which includes both two distinct nonlinear sums without an assumption of monotonicity and a nonconstant term outside the sums.

Equisizable partial sum families
, 2019 We introduce a special kind of partial sum families, which we call equisizable partial sum families, that can be used to obtain directed strongly regular graphs admitting a semiregular group of automorphisms.

Partial Differential Equations in Zero-Sum Differential Game and Applications on Coronavirus
Journal of Mathematics, 2023 In this paper, we studied a zero-sum game described by the partial differential equations as an application on Coronavirus. The game contains two players, player 1 is Coronavirus and player 2 is the population. We used ∞-Laplacian which is denoted by ∆∞.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

On Generalized One-kZero Numbers
AxiomsIn this study is introduced a novel generalization of repunit and one-zero numbers through the formulation of the generalized One-kZero. This sequence extends the classical families of repunit and one-zero numbers by establishing a unified framework in ...
