International Workshop on Variational Inequalities, Nash Equilibrium Problems and Applications (VINEPA 2024)

The workshop aims at presenting the state-of-the-art and current research on variational inequalities, Nash equilibrium problems and applications. Recently, there has been a sharp increase in interest in variational inequalities. They are now one of the most challenging and dynamic topics of mathematics, and represent excellent tools in the study of real-world problems. In fact, they cover a large variety of applications of extreme importance related to engineering, computer science, mathematical physics, statistics, economics, financial networks and generalized complementarity problems. In addition, Nash equilibrium problems, naturally associated with variational inequalities, experienced a surprising development. This leads to finding effective solutions to until now unsolved problems in numerous real-life situations, such as oligopoly models, environmental problems, network problems and infrastructure problems. Variational methods and game theory are also used in resource orchestration in a 5G/6G environment for creating and managing network slices, NVFs or services; in network optimization problems, with applications to logistics and transportation, to improve the eco-sustainability of last mile logistics using UAVs; in computer vision, machine learning, pattern recognition and artificial intelligence.

The aim of the workshop is to bring together scholars working on both theoretical and computational issues, present results having the potential of solving concrete problems, and thus try to fill the gap between theory and practice. 

Papers are solicited in, but not limited to, the following TOPICS:

  • Variational and quasi-variational inequalities
  • Nash and generalized Nash equilibrium problems
  • Equilibrium problems on networks both in the static and dynamic case
  • Generalized complementarity problems
  • Infinite-dimensional duality theory
  • Approximation and algorithms
  • Variational methods for 5G/6G networks, logistics and transportation with UAVs
  • Variational methods in computer vision, in machine learning, pattern recognition and artificial intelligence
  • Game theory in 5G/6G networks, logistics and transportation with UAVs
  • Game theory in computer vision, machine learning, pattern recognition and artificial intelligence
  • Applications to engineering, computer science, management science, transportation, economics, environmental problems, biology, telecommunications networks, etc.
