Project summary and objectives

---

 

The project is mainly motivated by the growing interest in the literature regarding sensitivity, openness/metric regularity, variational principles, and practical applications concerning equilibrium and optimization problems, interest which clearly shows that these fields are appropriate for applying the modern tools of nonlinear analysis. The aim of the seven objectives of the project  is to bring  to light new concepts and approaches within the following specific topics: parametric equilibrium problems, variational principles for equilibrium problems, vector optimization problems in connection with differential inclusions, duality and optimality conditions for set-valued optimization, numerical methods for equilibrium problems, interior-point methods for scalar optimization problems, algorithms for image processing, optimal location, and traffic flow optimization. The specific objectives of our project are:

 

O1.Parametric equilibrium problems;

O2.Variational principles for vector equilibrium problems;

O3.Vector optimization problems in connection with differential inclusions;

O4.Duality and optimality conditions for set-valued optimization;

O5.Numerical methods for equilibrium problems;

O6.Interior-point methods for scalar optimization problems;

O7.Algorithms for image processing and optimal location;
