Solutions of the Hammerstein equations in BVφ(IAB,R)
Journal Title: Discussiones Mathematicae Differential Inclusions Control and Optimization - Year 2016, Vol 36, Issue 2
Abstract
In this paper we study existence and uniqueness of solutions for the Hammerstein equation u(x)= v(x) + λ ∫_{I_{a}^{b}}K(x,y)f(y,u(y))dy in the space of function of bounded total φ-variation in the sense of Hardy-Vitali-Tonelli, where λϵR, K:I_a^b× I_a^b→ R and f:I_a^b× R→R are suitable functions. The existence and uniqueness of solutions are proved by means of the Leray-Schauder nonlinear alternative and the Banach contraction mapping principle.

Entropy solution for doubly nonlinear elliptic anisotropic problems with Fourier boundary conditions
The goal of this paper is to study nonlinear anisotropic problems with Fourier boundary conditions. We first prove, by using the technic of monotone operators in Banach spaces, the existence of weak solutions, and by app...
Upper and Lower Solutions Method for Partial Discontinuous Fractional Differential Inclusions with not Instantaneous Impulses
In this paper, we use the upper and lower solutions method combined with a fixed point theorem for multivalued maps in Banach algebras due to Dhage for investigations of the existence of solutions of a class of discontin...
On Schur-Cohn Stability of a Product of Operators in a Hilbert Space
A linear operator is said to be a Schur-Cohn stable one if its spectral radius is less than one. We consider the following problem: let A and B be bounded linear operators in a Hilbert space, and A be Schur-Cohn stable....
Pointwise strong approximation of almost periodic functions
We consider the class GM(2β) in pointwise estimate of the deviations in strong mean of almost periodic functions from matrix means of partial sums of their Fourier series.
Random integral guiding functions with application to random differential complementarity systems
By applying the random topological degree we develop the methods of random smooth and nonsmooth integral guiding functions and use them for the study of random differential inclusions in finite dimensional spaces. Some e...
