comment Barrier cone of a convex set. Why it is a cone?
Thank you for the explanation. I thought that $\beta$ should be the same for all $x^*$. Is it correct that a barrier cone for a bounded convex set is whole $\mathbb{R}^n$?

Ah, it is easy. sorry!

$L_1$ part I understood. It is a nice trick to split the integration range. To my shame I do not see why it is integrable in $L_2$. Integral $\int 1/x^2 dx$ does not converge.

I ``cooked'' such distribution based on what I need. If you put your comment as an answer I will accept it. You gave a reference to the Stieljes measure which is nice.
