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

Extremal Solutions of Nonlinear Impulsive Integrodifferential Equations in Banach Spaces
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]
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
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.
