A First-Order Method for Nonconvex-Nonconcave Minimax Problems under a Local Kurdyka–Łojasiewicz Condition

Abstract. We study a class of nonconvex-nonconcave minimax problems in which the inner maximization problem satisfies a local Kurdyka–Łojasiewicz (KL) condition that may vary with the outer minimization variable. In contrast to the global KL or Polyak–Łojasiewicz conditions commo...
