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 setvalued
optimization, numerical methods for equilibrium problems, interiorpoint
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 setvalued optimization;
O5.Numerical methods for equilibrium problems;
O6.Interiorpoint methods for scalar optimization
problems;
O7.Algorithms for image
processing and optimal location;
