We investigate the asymptotic properties of the inhomogeneous nonautonomous evolution equation (d/dt)u(t) = Au(t) + B(t)u(t) + f(t), t ∈ ℝ, where (A, D(A)) is a Hille‐Yosida operator on a Banach space X, B(t), t ∈ ℝ, is a family of operators in ℒ(D(A)¯,X) satisfying certain boundedness and measurability conditions and f∈L loc 1(ℝ,X).

Existence of periodic solutions with prescribed minimal period of a 2nth-order discrete system
In this paper, we concern with a 2nth-order discrete system. Using the critical point theory, we establish various sets of sufficient conditions for the existence of periodic solutions with prescribed minimal period. To the best of our knowledge, this is

Periodic solutions of quasi‐differential equations
Existence principles and theorems are established for the nonlinear problem Lu = f(t, u) where Lu=−(pu′) ′+hu is a quasi‐differential operator and f is a Carathéodory function. We prove a maximum principle for the operator L and then we show the validity of the upper and lower solution method as well as the monotone iterative technique.

Homoclinic solutions for a differential inclusion system involving the p(t)-Laplacian
The aim of this article is to study nonlinear problem driven by the p(t)p\left(t)-Laplacian with nonsmooth potential. We establish the existence of homoclinic solutions by using variational principle for locally Lipschitz functions and the properties of ...

Multiplicity of positive solutions to second-order singular differential equations with a parameter
We study the existence and multiplicity of positive periodic solutions for second-order nonlinear damped differential equations by combing the analysis of positiveness of the Green function for a linear damped equation.

The analogue of the Floquet-Lyapunov theorem for the linear differential systems of the special kind
The analogue of the well known in the theory of the linear differential systems Floquet’s– Lyapunov’s theorem are constructed by the certain condidtions for the linear differential system, whose coefficients are represented as an absolutely and uniformly

Nonresonance conditions for fourth order nonlinear boundary value problems
This paper is devoted to the study of the problem We assume that f can be written under the form where r is a bounded function. We obtain existence conditions related to uniqueness conditions for the solution of the linear problem

Local dynamics for fibered holomorphic transformations [PDF]
Fibered holomorphic dynamics are skew-product transformations over an irrational rotation, whose fibers are holomorphic functions. In this paper we study such a dynamics on a neighborhood of an invariant curve. We obtain some results analogous to the results in the non fibered case.
