On Semilinear Integro-Differential Equations with Nonlocal Conditions in Banach Spaces

open access: yesAbstract and Applied Analysis, 2012
We study the abstract Cauchy problem for a class of integrodifferential equations in a Banach space with nonlinear perturbations and nonlocal conditions. By using MNC estimates, the existence and continuous dependence results are proved.

Self‐Similar Blowup for the Cubic Schrödinger Equation

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1831-1918, August 2026.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Analysis of Implicit Neutral-Tempered Caputo Fractional Volterra–Fredholm Integro-Differential Equations Involving Retarded and Advanced Arguments

open access: yesMathematics
This paper investigates a class of implicit neutral fractional integro-differential equations of Volterra–Fredholm type. The equations incorporate a tempered fractional derivative in the Caputo sense, along with both retarded (delay) and advanced ...

Extremal Solutions of Nonlinear Impulsive Integrodifferential Equations in Banach Spaces

open access: yesJournal of Mathematical Analysis and Applications, 1993
The authors utilize the monotone iterative technique with fixed point theory to investigate the extremal solutions of nonlinear impulsive integro-differential equations in Banach spaces. Existence criteria are obtained and several examples are worked out to illustrate the results.

Nonlinear perturbations and abstract evolution equations in general banach spaces [PDF]

open access: yesAnnali di Matematica Pura ed Applicata, 1976
Part I deals with the problem of determining sufficient conditions under which the sum of two m-accretive operators on a closed convex set Q1 is m-accretive on Q1. Part II is concerned with the initial value problem: u′+Au+g(u)=v, u(0)=u0. Applications are given to the Boltzmann equation.

Local Convergence of Jarratt-Type Methods with Less Computation of Inversion Under Weak Conditions

open access: yesMathematical Modelling and Analysis, 2017
We present a local convergence analysis for Jarratt-type methods in order to approximate a solution of a nonlinear equation in a Banach space setting. Earlier studies cannot be used to solve equations using such methods.
