Exponential Dichotomies by Ekeland’s Variational Principle
Journal of Dynamics and Differential Equations, 2020Exponential dichotomy, which is a type of hyperbolicity in the context of linear time-varying systems, is the central focus of this paper. First, two well known characterizations of the exponential dichotomy in \(\mathbb{R}^+\) are presented: \begin{itemize} \item [(i)] If the system \(\dot{v}=A(t)v+f(t)\) in \(\mathbb{R}^N\), admits a bounded solution

In this chapter we present existence results for minimal points of subsets of the Cartesian product of a complete metric space and a topological vector space with respect to order relations determined by generalized set-valued metrics; such results are useful for deriving EVP type results for vector and scalar functions.

On Ekeland's Variational Principle for Set-Valued Mappings
Acta Mathematicae Applicatae Sinica, English Series, 2007Let \(X\) be a complect metric space and \(E\) be an ordered Hausdorff topological vector space. In this paper for new classes of set valued mappings \(F:X \rightarrow 2^{E}\) the vector Ekeland's variation principle is proved.

Vector Ekeland Variational Principle
2000In this paper the well-known Ekeland variational principle is generalized to the case where vector-valued functions are involved. Namely, vector Ekeland variational principle is studied. In particular, the epsilon vector minimum point of a vector optimization problem is investigated via vector Ekeland variational principle.

Ekeland’s Variational Principle for Functions Unbounded from below
The interdisciplinary journal of Discontinuity, Nonlinearity, and Complexity, 2020This paper is devoted to variational principles of nonlinear analysis for functions whose domain is a generalized metric space. A modification of the Ekeland variational principle for functions unbounded from below is obtained. For a wide class of differentiable functions not necessarily bounded below, it is shown that there exists a minimizing ...
