Aha! I see. I got it now. Thank you, you have saved my day :)

i can see the intuitive behind it now. But when i have shown that this distance grow larger, what's next? Where are we heading?

hmm i can't quite see the trick. But K has no direction because it is compact?

Thanks for your reply :) and yes, a characteristic cone is the same as a recession cone. Then I must show that T = S I can show that if a belongs to S, then a must belong to T as well. Let a=y+d belong to C. if y belongs to C, and because C \subseteq C+K, then y must belong to C+K...

Hello :) I have been giving a mathematical problem. But I find difficulties solving this. Therefore, I will be very grateful if anybody might wanted to help? The problem is "Let K be a compact convex set in R^n and C a closed convex cone in R^n. Show that ccone (K + C) = C." - Julie.
