International Journal of Mathematics and Mathematical Sciences, Volume 2024, Issue 1, 2024.In this article, the focus is on investigating the uniqueness, existence, and stability of a coupled system of fractional differential equations with non‐separated coupled boundary conditions. The uniqueness of solutions for the presented problem is discussed by employing the fixed‐point theorem.

Journal of Function Spaces, 2018 We deal with a singular nonlocal fractional differential equation with Riemann-Stieltjes integral conditions. The exact iterative solution is established under the iterative technique. The iterative sequences have been proved to converge uniformly to the

XML Data Integrity Based on Concatenated Hash Function [PDF]
IJCSIS, May 2009, Vol. 1, 2009 Data integrity is the fundamental for data authentication. A major problem for XML data authentication is that signed XML data can be copied to another document but still keep signature valid. This is caused by XML data integrity protecting. Through investigation, the paper discovered that besides data content integrity, XML data integrity should also ...

QYMSYM: A GPU-Accelerated Hybrid Symplectic Integrator That Permits Close Encounters [PDF]
, 2010 We describe a parallel hybrid symplectic integrator for planetary system integration that runs on a graphics processing unit (GPU). The integrator identifies close approaches between particles and switches from symplectic to Hermite algorithms for particles that require higher resolution integrations.

Vestnik Udmurtskogo Universiteta Matematika Mekhanika Komp yuternye NaukiIn the previous work of the authors, the concept of a regulated function of several variables $f\colon X\to\mathbb R$ was introduced, where $X\subseteq \mathbb R^n.$ The definition is based on the concept of a special partition of the set $X$ and the ...

Econometrica, Volume 92, Issue 1, Page 167-200, January 2024.We formulate an order over constraint sets , called the parallelogram order, which guarantees that argmin{p ⋅ x:x ∈ A} increases in the product order as A increases in the parallelogram order, for any vector . Using this result, we characterize the utility/production functions that lead to normal demand as well as the closely related class of ...

Weierstrass integrability of differential equations [PDF]
arXiv, 2009 The integrability problem consists in finding the class of functions a first integral of a given planar polynomial differential system must belong to. We recall the characterization of systems which admit an elementary or Liouvillian first integral.

Frequency-domain analysis of nonlinear and linear integrators [PDF]
arXiv, 2015 In this paper, frequency-domain analysis based on frequency sweep method is presented for a nonlinear double integrator and a new linear integrator. All the two types of integrators can estimate the onefold and double integrals of a signal synchronously.

A Sharp Bound of the Čebyšev Functional for the Riemann-Stieltjes Integral and Applications
Journal of Inequalities and Applications, 2008 A new sharp bound of the Čebyšev functional for the Riemann-Stieltjes integral is obtained. Applications for quadrature rules including the trapezoid and midpoint rules are given.
