Applications of Modified Bessel Polynomials to Solve a Nonlinear Chaotic Fractional-Order System in the Financial Market: Domain-Splitting Collocation Techniques

open access: yesComputation, 2023
We propose two accurate and efficient spectral collocation techniques based on a (novel) domain-splitting strategy to handle a nonlinear fractional system consisting of three ODEs arising in financial modeling and with chaotic behavior.

The matrix rate of return [PDF]

open access: yes, 2006
In this paper we give definitions of matrix rates of return which do not depend on the choice of basis describing baskets. We give their economic interpretation. The matrix rate of return describes baskets of arbitrary type and extends portfolio analysis

The binomial sequence spaces of nonabsolute type

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we introduce the binomial sequence spaces b 0 r , s $b^{r,s}_{0}$ and b c r , s $b^{r,s}_{c}$ of nonabsolute type which include the spaces c 0 $c_{0}$ and c, respectively.

Effect of Wavelet Selection on Periodic Steady-State Analysis

open access: yesIEEE Access, 2020
This paper presents a study of the effect wavelet selection has on the density of the Jacobian matrix and nodal waveform coefficients of wavelet based periodic steady-state analysis of electrical circuits. For the presented case studies, it is shown that

υ-representability of one-body density matrices [PDF]

open access: yes, 2001
We consider low-dimensional model systems with a fixed two-body interaction and a variable (nonlocal) one-body potential. It is shown explicitly that an extended domain of allowed (N-representable) one-body density matrices cannot be generated in this ...

A Note on the Sequence Space b_p^(r,s) (G)

open access: yesCumhuriyet Science Journal, 2017
In this study, we define the sequence space  derived by the composition of the Binomialmatrix and generalized difference(double band) matrix and show that the space  is linearly isomorphic to the space , where .

An Improved Traffic Matrix Decomposition Method with Frequency-Domain Regularization

open access: yes, 2012
We propose a novel network traffic matrix decomposition method named Stable Principal Component Pursuit with Frequency-Domain Regularization (SPCP-FDR), which improves the Stable Principal Component Pursuit (SPCP) method by using a frequency-domain noise

Kato square root problem with unbounded leading coefficients [PDF]

open access: yes, 2017
We prove the Kato conjecture for elliptic operators, $L=-\nabla\cdot\left((\mathbf A+\mathbf D)\nabla\ \right)$, with $\mathbf A$ a complex measurable bounded coercive matrix and $\mathbf D$ a measurable real-valued skew-symmetric matrix in $\mathbb{R}^n$
