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

Integer Factorization with Compositional Distributed Representations

open access: yesNeuro-Inspired Computational Elements Conference, 2022
In this paper, we present an approach to integer factorization using distributed representations formed with Vector Symbolic Architectures. The approach formulates integer factorization in a manner such that it can be solved using neural networks and potentially implemented on parallel neuromorphic hardware.

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 ...

On the basis number of the composition of different ladders with some graphs

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
The basis number b(G) of a graph G is defined to be the least integer k such that G has a k-fold basis for its cycle space. In this paper, we investigate the basis number of the composition of paths and cycles with ladders, circular ladders, and Möbius ...

Crashing Construction Project Schedules by Relocating Resources

open access: yesIEEE Access, 2020
A variety of schedule compression techniques are used to get delayed construction projects “back on tracks”. This paper presents a new optimization approach to schedule crashing by relocating some of the workers from non-critical to ...

Statistics for 3-letter patterns with repetitions in compositions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2016
A composition $\pi = \pi_1 \pi_2 \cdots \pi_m$ of a positive integer $n$ is an ordered collection of one or more positive integers whose sum is $n$. The number of summands, namely $m$, is called the number of parts of $\pi$.

Arndt and De Morgan Integer Compositions

open access: yes, 2023
In 2013, Joerg Arndt recorded that the Fibonacci numbers count integer compositions where the first part is greater than the second, the third part is greater than the fourth, etc. We provide a new combinatorial proof that verifies his observation using compositions with only odd parts as studied by De Morgan.
