First, I wonder whether I can put the post here...
Given
X=[0,1]^2
a(x)={y in X:||y-x||>=1/4}
b(x)is the convex hull of a(x).
Identify the set of fixed points.
My answer is 3/4>=x>=1/4, 3/4>=y>=1/4, but I am not sure...
What if we have a(x)={y in X:||y-x||>=1/2}? (My answer is x=1/2 or y=1/2)
Thanks.
