Variable s0 s2 : Site.
Hypothesis rt_true : rt c0 s2 = false.
Hypothesis first_mess : first Message (bm c0 owner s2) = value Message copy.
Remark rcop2_trans_xi :
forall s1 : Site, xi (rec_copy2_trans c0 s2) s1 = xi c0 s1.
Remark rcop2_trans_yi :
forall s1 : Site, yi (rec_copy2_trans c0 s2) s1 = yi c0 s1.

Lemma rcop2_trans_sigma_xi : sigma_xi (rec_copy2_trans c0 s2) = sigma_xi c0.
