A second‐order impulsive Cauchy problem
International Journal of Mathematics and Mathematical Sciences, Volume 31, Issue 8, Page 451-461, 2002., 2002 We study the existence of mild and classical solutions for an abstract second‐order impulsive Cauchy problem modeled in the form u¨(t)=A u(t)+f(t,u(t),u˙(t)),t∈(−T0,T1),t≠ti;u(0)=x0,u˙(0)=y0; △u(ti)=Ii1 (u (ti)). △u˙(ti)=Ii2 (u˙ (ti+)) where A is the infinitesimal generator of a strongly continuous cosine family of linear operators on a Banach space X ...

Existence of solutions for delay evolution equations with nonlocal conditions
Open Mathematics, 2017 In this paper, we are devoted to study the existence of mild solutions for delay evolution equations with nonlocal conditions. By using tools involving the Kuratowski measure of noncompactness and fixed point theory, we establish some existence results ...

Impulsive functional‐differential equations with nonlocal conditions
International Journal of Mathematics and Mathematical Sciences, Volume 29, Issue 5, Page 251-256, 2002., 2002 The existence, uniqueness, and continuous dependence of a mild solution of an impulsive functional‐differential evolution nonlocal Cauchy problem in general Banach spaces are studied. Methods of fixed point theorems, of a C0 semigroup of operators and the Banach contraction theorem are applied.

A Taylor-type numerical method for solving nonlinear ordinary differential equations
Alexandria Engineering Journal, 2013 A novel approximate method is proposed for solving nonlinear differential equations. Chang and Chang in [8] suggested a technique for calculating the one-dimensional differential transform of nonlinear functions.

Existence of Solutions of a Class of Abstract Second Order Nonlinear Integrodifferential Equations
International Journal of Stochastic Analysis, Volume 15, Issue 2, Page 115-124, 2002., 2002 In this paper we prove the existence of solutions of nonlinear second order integrodifferential equations in Banach spaces. The results are obtained by using the theory of strongly continuous cosine families of operators and the Schaefer fixed point theorem.

On the correct formulation of a nonlinear differential equations in Banach space
International Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 7, Page 437-444, 2001., 2001 We study, the existence and uniqueness of the initial value problems in a Banach space E for the abstract nonlinear differential equation (dn−1/dtn−1)(du/dt + Au) = B(t)u + f(t, W(t)), and consider the correct solution of this problem. We also give an application of the theory of partial differential equations.
