- Abstract
- In this paper, we proposed a modified subgradient extragradient method for dealing with pseudomonotone equilibrium problems involving Lipschitz-type condition on a cost bifunction in a real Hilbert space. The weak convergence theorem for the method is precisely provided based on the standard assumptions on the cost bifunction. For a numerical experiment, we consider the well-known Nash-Cournot oligopolistic equilibrium models and other examples to support our established convergence results.
