A variational principle for certain dissipative evolution equations

open access: yes, 2003
We formulate a variational principle which models several first order parabolic Cauchy problems. Unlike the one proposed by Brezis-Ekeland in [2], this principle does not require the identification of the extremal value, which was a major hurdle for ...

Exponential Dichotomies by Ekeland’s Variational Principle

Journal of Dynamics and Differential Equations, 2020
Exponential 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

Vectorial form of Ekeland-type variational principle with applications to vector equilibrium problems and fixed point theory

open access: yesJournal of Mathematical Analysis and Applications, 2007

Ekeland Variational Principle

2014
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, 2007
Let \(X\) 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.
