Abstract :
A novel method for establishing the optimality of Gaussian auxiliary random variables in multiterminal information theory problems is developed. This method is then employed to show that Marton´s inner bound achieves the capacity region of the two-receiver Gaussian vector broadcast channel with private and common messages.
