Lipschitz modulus of convex functions via function values
摘要
In this paper, we establish the Lipschitz continuity of finite-dimensional globally convex functions on all given balls and global Lipschitz continuity for eligible functions of that type. The Lipschitz constants in both situations draw information solely from function values, and the global Lipschitz modulus is found when it exists. Some examples of classes of globally Lipschitz continuous convex functions besides the norms are also provided along with their global Lipschitz modulus.
