# colouring properties of functions

on page 5 (857) here

in the definition $$AR_1^+$$

isn't there missing

$$\max$$

right before $$x+1$$

?

It should read $$\max C(x)\leq \max x+1$$

because on the left hand side there is "x" bounded but on r.h.s. it is not. With this $$\max$$ it is more akin to page 2 "limited".
