Variational Principle for Weakly Dependent Random Fields

open access: yes, 2020
Using an alternative notion of entropy introduced by Datta, the max-entropy, we present a new simplified framework to study the minimizers of the specific free energy for random fields which are weakly dependent in the sense of Lewis, Pfister, and ...

Increase-along-rays property for vector functions [PDF]

open access: yes
In this paper we extend to the vector case the notion of increasing along rays function. The proposed definition is given by means of a nonlinear scalarization through the so-called oriented distance function from a point to a set.

Ekeland Type Variational Principle with Applications to Quasi-variational Inclusion Problems

open access: yes, 2011
[[abstract]]In this paper, we study the Ekeland type variational principle, a Caristi Kirk type fixed point theorem and a maximal element theorem in the setting of uniform spaces.

Borwein-Preiss variational principle revisited

open access: yes, 2016
In this article, we refine and slightly strengthen the metric space version of the Borwein-Preiss variational principle due to Li and Shi (2000) [12], clarify the assumptions and conclusions of their Theorem 1 as well as Theorem 2.5.2 in Borwein and Zhu (
