Error bounds of lower semi-continuous convex-along-rays functions

In this paper, we study Lipschitz global error bounds for lower semi-continuous convex-along-rays (l.s.c. CAR) functions. We find a condition that ensures the existence of a global error bound for a CAR function. Moreover, we find a condition under which an l.s.c. CAR function does not have a Lipschitz global error bound. Finally, we survey Lipschitz’s global error bounds of an l.s.c. (in particular, an l.s.c. CAR) function from the perspective of abstract convexity.
