Nonlinear Integrodifferential Equations of Mixed Type in Banach Spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
We prove two existence theorems for the integrodifferential equation of mixed type:x'(t)=f(t,x(t),∫0tk1(t,s)g(s,x(s))ds,∫0ak2(t,s)h(s,x(s))ds),x(0)=x0, where in the first part of this paperf, g, h, xare functions with values in a Banach spaceEand integrals are taken in the sense of Henstock-Kurzweil (HK).

Existence and Boundedness of Solutions for Nonlinear Volterra Difference Equations in Banach Spaces

open access: yesAbstract and Applied Analysis, 2016
We consider a class of nonlinear discrete-time Volterra equations in Banach spaces. Estimates for the norm of operator-valued functions and the resolvents of quasi-nilpotent operators are used to find sufficient conditions that all solutions of such ...

Nonlinear evolution equations on Banach space [PDF]

open access: yesInternational Journal of Stochastic Analysis, 1991
In this paper we consider the questions of existence and uniqueness of solutions of certain semilinear and quasilinear evolution equations on Banach space. We consider both deterministic and stochastic systems. The approach is based on semigroup theory and fixed point theorems.

Local existence result of the single dopant diffusion including cluster reactions of high order

open access: yesAbstract and Applied Analysis, 2001
We consider the pair diffusion process which includes cluster reactions of high order. We are able to prove a local (in time) existence result in arbitrary space dimensions.

Generalizations of the Lax-Milgram Theorem

open access: yesBoundary Value Problems, 2007
We prove a linear and a nonlinear generalization of the Lax-Milgram theorem. In particular, we give sufficient conditions for a real-valued function defined on the product of a reflexive Banach space and a normed space to represent all bounded linear ...

A Class of Fractional p-Laplacian Integrodifferential Equations in Banach Spaces

open access: yesAbstract and Applied Analysis, 2013
We study a class of nonlinear fractional integrodifferential equations with p-Laplacian operator in Banach space. Some new existence results are obtained via fixed point theorems for nonlocal boundary value problems of fractional p-Laplacian equations ...
