Prime ideal on the end_Z (Z^n ) Ring

open access: yesAl-Jabar, 2022
The set of all endomorphisms over -module  is a non-empty set denoted by . From  we can construct the ring of  over addition and composition function. The prime ideal is an ideal which satisfies the properties like the prime numbers.

Composite Fermions and Integer Partitions

open access: yesJournal of Combinatorial Theory, Series A, 2001
The authors prove the unimodality of integer partitions with at most \(a\) parts, all parts less than or equal to \(b\), that are required to contain either repeated or consecutive parts. The proof uses the KOH theorem [\textit{D. Zeilberger}, Am. Math. Mon. 96, No. 7, 590-602 (1989; Zbl 0726.05005)].

Compositions of integers and Fibonacci numbers

open access: yesCommunications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2023
In this paper, we deal with the compositions of the integers. We present the decompositions for both the composition sets and the odd composition sets of the integers. Thus the decompositions provide us to have not only an alternative proof of some well known identies but also many new identities for Fibonacci numbers and Lucas numbers.

Probabilistic Analysis of CarlitzCompositions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2002
Using generating functions and limit theorems, we obtain a stochastic description of Carlitz compositions of large integer n (i.e. compositions two successive parts of which are different).

Solving nonlinear optimization problems with bipolar fuzzy relational equation constraints

open access: yesJournal of Inequalities and Applications, 2016
This paper considers the problem of minimizing a nonlinear objective function subject to a system of bipolar fuzzy relational equations with max- T L $T_{L}$ composition, where T L $T_{L}$ is the Łukasiewicz triangular norm.

The Distribution of Run Lengths in Integer Compositions [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2011
We find explicitly the generating function for the number of compositions of $n$ that avoid all words on a given list of forbidden subwords, in the case where the forbidden words are pairwise letter-disjoint. From this we get the gf for compositions of $n$ with no $k$ consecutive parts equal, as well as the number with $m$ parts and no consecutive $k ...

Subnormal Weighted Shifts on Directed Trees and Composition Operators in L2-Spaces with Nondensely Defined Powers

open access: yesAbstract and Applied Analysis, 2014
It is shown that for every positive integer n there exists a subnormal weighted shift on a directed tree (with or without root) whose nth power is densely defined while its (n+1)th power is not. As a consequence, for every positive integer n there exists

Optimal error estimate of the Legendre spectral approximation for space-fractional reaction–advection–diffusion equation

open access: yesAdvances in Difference Equations, 2018
In this paper, we consider the space-fractional reaction–advection–diffusion equation with fractional diffusion and integer advection terms. By treating the first-order integer derivative as the composition of two Riemann–Liouville fractional derivative ...

New techniques for cost sharing in combinatorial optimization games [PDF]

open access: yes, 2010
Combinatorial optimization games form an important subclass of cooperative games. In recent years, increased attention has been given to the issue of finding good cost shares for such games.
