 multiple-access channel (MAC) with feedback. The bound is based on depende
 nce-balance constraint. An essential ingredient to prove the bound is the 
 method known in the literature as "doubling trick'' which is used to prove
  optimality of Gaussian auxiliary random variables. For the Gaussian MAC w
 ith equal transmitter powers\, the bound promises to be the feedback sum-r
 ate capacity.\n\nBacground papers\nFeedback Can at Most Double Gaussian Mu
