Fixed points of dynamic processes of set-valued F-contractions and application to functional equations [PDF]

open access: yes, 2015
The article is a continuation of the investigations concerning F-contractions which have been recently introduced in [Wardowski in Fixed Point Theory Appl. 2012:94,2012]. The authors extend the concept of F-contractive mappings to the case of nonlinear F-

An iterative method for variational inequality problems

open access: yesJournal of Inequalities and Applications, 2013
In this paper, we present some properties of generalized proximity operators andpropose an iterative method of approximating solutions for a class ofgeneralized variational inequalities and show its convergence in uniformlyconvex and smooth Banach spaces.

Lagrange optimality system for a class of nonsmooth convex optimization [PDF]

open access: yes, 2015
In this paper, we revisit the augmented Lagrangian method for a class of nonsmooth convex optimization. We present the Lagrange optimality system of the augmented Lagrangian associated with the problems, and establish its connections with the standard ...

Optimal transportation with an oscillation-type cost: the one-dimensional case [PDF]

open access: yes, 2012
The main result of this paper is the existence of an optimal transport map $T$ between two given measures $\mu$ and $\nu$, for a cost which considers the maximal oscillation of $T$ at scale $\delta$, given by $\omega_\delta(T):=\sup_{|x-y|

Are law-invariant risk functions concave on distributions?

open access: yesDependence Modeling, 2013
While it is reasonable to assume that convex combinations on the level of random variables lead to a reduction of risk (diversification effect), this is no more true on the level of distributions.

Mathematical Model Creation for Cancer Chemo‐Immunotherapy

open access: yesComputational and Mathematical Methods in Medicine, Volume 10, Issue 3, Page 165-184, 2009., 2009
One of the most challenging tasks in constructing a mathematical model of cancer treatment is the calculation of biological parameters from empirical data. This task becomes increasingly difficult if a model involves several cell populations and treatment modalities.

Purely finitely additive measures as generalized elements in a maximin problem [PDF]

open access: yes, 2013
We study the asymptotic behavior of maximin values of a payoff function, when admissible controls tend to infinity. The payoff function is superposition of a continuos function and a function that is uniform limit of step functions.

Coincidence theorems for families of multimaps and their applications to equilibrium problems

open access: yesAbstract and Applied Analysis, Volume 2003, Issue 5, Page 295-309, 2003., 2003
We apply some continuous selection theorems to establish coincidence theorems for a family of multimaps under various conditions. Then we apply these coincidence theorems to study the equilibrium problem with m families of players and 2m families of constraints on strategy sets.

On projection constant problems and the existence of metric projections in normed spaces

open access: yesAbstract and Applied Analysis, Volume 6, Issue 7, Page 401-411, 2001., 2001
We give the sufficient conditions for the existence of a metric projection onto convex closed subsets of normed linear spaces which are reduced conditions than that in the case of reflexive Banach spaces and we find a general formula for the projections onto the maximal proper subspaces of the classical Banach spaces l p, 1 ≤ p < ∞ and c 0.

Paraconvex functions and paraconvex sets

open access: yes, 2008
We study a class of functions which contains both convex functions and differentiable functions whose derivatives are locally Lipschitzian or Holderian. This class is a subclass of the class of approximately convex functions. It enjoys refined properties.
