Convergence of a Two-Stage Proximal Algorithm for the Equilibrium Problem in Hadamard Spaces.

An iterative two-stage proximal algorithm for approximate solution of equilibrium problems in Hadamard spaces is considered. This algorithm is an analog of the already studied two-stage algorithm for equilibrium problems in a Hilbert space. For Lipschitz-type pseudo-monotone bifunctions, a theorem on the weak convergence of sequences generated by the algorithm is proved. [ABSTRACT FROM AUTHOR]
