Query: An information inequality and evaluation of Marton's inner bound for
  binary input broadcast channels   We establish an information inequality that is intimately connected to the
evaluation of the sum rate given by Marton's inner bound for two receiver
broadcast channels with a binary input alphabet. This generalizes a recent
result where the inequality was established for a particular channel, the
binary skew-symmetric broadcast channel. The inequality implies that randomized
time-division strategy indeed achieves the sum rate of Marton's inner bound for
all binary input broadcast channels.
