Finite size corrections on the boundary between the spin-glass and the   ferromagnetic phases of Derrida's model
  The boundary line between the ferromagnetic and the spin-glass phases was investigated. Finite size corrections to the free energy and magnetization were calculated. The situation coincides with the case in the information theory, when the transmission rate equals to the capacity of channel.
