On the Existence of Solutions of Nonlinear Fredholm Integral Equations from Kantorovich’s Technique
Algorithms, 2017 The well-known Kantorovich technique based on majorizing sequences is used to analyse the convergence of Newton’s method when it is used to solve nonlinear Fredholm integral equations. In addition, we obtain information about the domains of existence and

Prolongations of integral domains
Journal of Algebra, 1985 The motivation for this rather extensive and complicated paper is derived from the purely algebraic approach to the theory of overdetermined systems of partial differential equations. A system of (algebraic) differential equations represents a set of elements \(F_ 1,F_ 2,...,F_ n\) of a polynomial ring \(P=k[\delta^ py_ j: p\in {\mathbb{N}}^ m, j=1,...,

On Generalized Bazilevic Functions Related with Conic Regions
Journal of Applied Mathematics, 2012 We define and study some generalized classes of Bazilevic functions associated with convex domains. These convex domains are formed by conic regions which are included in the right half plane.

Estimates for Generalized Parabolic Marcinkiewicz Integrals with Rough Kernels on Product Domains
Axioms, 2023 We prove Lp estimates of a class of generalized Marcinkiewicz integral operators with mixed homogeneity on product domains. By using these estimates along with an extrapolation argument, we obtain the boundedness of our operators under very weak ...

On the Graph of Divisibility of an Integral Domain [PDF]
Canadian Mathematical Bulletin, 2015 AbstractIt is well known that the factorization properties of a domain are reflected in the structure of its group of divisibility. The main theme of this paper is to introduce a topological/graph-theoretic point of view to the current understanding of factorization in integral domains.

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011 The one-valued solvability of the conjugation problems of parabolic and hyperbolic equations in finite domains was proved by the method of equivalent reduction to Volterra integral equation of the second kind.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Next‐generation sequencing (NGS) has emerged as a promising approach to improve diagnostic accuracy, but its feasibility in low‐ and middle‐income countries remains unknown. This study characterized the diagnostic landscape and assessed organizational readiness for NGS implementation at two childhood cancer treatment centers in Accra ...
