Calculus rules of the generalized concave Kurdyka- ojasiewicz property
Abstract
In this paper, we propose several calculus rules for the generalized concave Kurdyka- ojasiewicz (KL) property, which generalize Li and Pong's results for KL exponents. The optimal concave desingularizing function has various forms and may be nondifferentiable. Our calculus rules do not assume desingularizing functions to have any specific form nor differentiable, while the known results do. Several examples are also given to show that our calculus rules are applicable to a broader class of functions than the known ones.
