A note on outer bounds for broadcast channel

Abstract

In this note we establish two facts concerning the so-called {\em New-Jersey} outer bound. We show that this outer bound is equivalent to a much simpler {\em computable} region; and secondly we show that in the absence of private information this bound is exactly same as the $UV$-outerbound.

This was presented in the International Zurich Seminar 2010. This is just for a documented proof of the result
