Solutions of a system of integral equations in orlicz spaces [PDF]
We consider the following system of integral equations u(i)(t) = integral(1)(0) g(i)(t, s)f(i) (s, u(1)(s), u(2)(s),...,u(n)(s)) ds, a.e. t is an element of [0,1].

We study minimax estimation of functionals of solutions to parabolic problems under nonlinear observations with rapidly oscillating coefficients. An averaging approach is developed, the existence of a minimax estimator is proved, and the convergence of ...

The authors consider a Volterra integrodifferential equation of any order and of the second kind. They obtain exact and approximate solutions in the field of Mikusinski's operators \(F\), or, more precise, in a subspace \(F_c=\{f\in F\}\), where \(f\) is represented by a continuous function.

ABSTRACT Background General pediatricians often evaluate hematologic and oncologic presentations before subspecialty consultation, yet the 2025 Accreditation Council for Graduate Medical Education (ACGME) pediatric requirements reduce inpatient pediatric hematology/oncology (PHO) time, raising questions about resident readiness.

Circulant integral operators as preconditioners for Wiener-Hopf equations [PDF]
In this paper, we study the solutions of finite-section Wiener-Hopf equations by the preconditioned conjugate gradient method. Our main aim is to give an easy and general scheme of constructing good circulant integral operators as preconditioners for ...

Solving linear Fredholm fuzzy integral equations of the second kind by artificial neural networks
This paper deals with the solutions of fuzzy Fredholm integral equations using neural networks. Based on the parametric form of a fuzzy number, a Fredholm fuzzy integral equation converts to two systems of integral equations of the second kind in the ...

On The Approximation Of Singular Integral Equations By Equations With Smooth Kernels [PDF]
Singular integral equations with Cauchy kernel and piecewise--continuous matrix coefficients on open and closed smooth curves are replaced by integral equations with smooth kernels of the form (t \Gamma ø )[(t \Gamma ø ) 2 \Gamma n 2 (t)" 2 ]
