M. Quatrini et Lt. Defalco, POLARIZATION OF CLASSICAL PROOFS AND REVE RSION, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 323(2), 1996, pp. 113-116
We introduce a new constraint on the proofs of the classical sequent c
alculus LK(pol)(eta) (eta-constrained and polarized). We obtain a comp
lete and stable fragment for which the P embedding into linear logic i
s a decoration.
