% 126.05/16.55  % SZS output start Proof
% 126.05/16.55  Take the following subset of the input axioms:
% 126.05/16.55    fof(cls_App_I3_J_0, axiom, c_Type_Otyping(v_ea____, v_ta____, v_Ta____)).
% 126.05/16.55    fof(cls_conjecture_0, negated_conjecture, ~c_Type_Otyping(c_Type_Oshift(v_ea____, c_HOL_Ozero__class_Ozero(tc_nat), hAPP(hAPP(c_Type_Otype_OFun, v_Ta____), v_U____), tc_Type_Otype), hAPP(hAPP(c_Lambda_OdB_OApp, c_Lambda_OdB_OVar(c_HOL_Ozero__class_Ozero(tc_nat))), c_Lambda_Olift(v_ta____, c_HOL_Ozero__class_Ozero(tc_nat))), v_U____)).
% 126.05/16.55    fof(cls_lift__type_0, axiom, ![V_i, V_t, V_e, V_T, V_U]: (c_Type_Otyping(c_Type_Oshift(V_e, V_i, V_U, tc_Type_Otype), c_Lambda_Olift(V_t, V_i), V_T) | ~c_Type_Otyping(V_e, V_t, V_T))).
% 126.05/16.55    fof(cls_shift__eq_0, axiom, ![T_a, V_x, V_T2, V_e2]: hAPP(c_Type_Oshift(V_e2, V_x, V_T2, T_a), V_x)=V_T2).
% 126.05/16.56    fof(cls_typing_OApp_0, axiom, ![V_s, V_T2, V_env, V_t2, V_U2]: (c_Type_Otyping(V_env, hAPP(hAPP(c_Lambda_OdB_OApp, V_s), V_t2), V_U2) | (~c_Type_Otyping(V_env, V_t2, V_T2) | ~c_Type_Otyping(V_env, V_s, hAPP(hAPP(c_Type_Otype_OFun, V_T2), V_U2))))).
% 126.05/16.56    fof(cls_typing_OVar_0, axiom, ![V_x2, V_env2]: c_Type_Otyping(V_env2, c_Lambda_OdB_OVar(V_x2), hAPP(V_env2, V_x2))).
% 126.05/16.56  
% 126.05/16.56  Now clausify the problem and encode Horn clauses using encoding 3 of
% 126.05/16.56  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 126.05/16.56  We repeatedly replace C & s=t => u=v by the two clauses:
% 126.05/16.56    fresh(y, y, x1...xn) = u
% 126.05/16.56    C => fresh(s, t, x1...xn) = v
% 126.05/16.56  where fresh is a fresh function symbol and x1..xn are the free
% 126.05/16.56  variables of u and v.
% 126.05/16.56  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 126.05/16.56  input problem has no model of domain size 1).
% 126.05/16.56  
% 126.05/16.56  The encoding turns the above axioms into the following unit equations and goals:
% 126.05/16.56  
% 126.05/16.56  Axiom 1 (cls_App_I3_J_0): c_Type_Otyping(v_ea____, v_ta____, v_Ta____) = true2.
% 126.05/16.56  Axiom 2 (cls_shift__eq_0): hAPP(c_Type_Oshift(X, Y, Z, W), Y) = Z.
% 126.05/16.56  Axiom 3 (cls_typing_OVar_0): c_Type_Otyping(X, c_Lambda_OdB_OVar(Y), hAPP(X, Y)) = true2.
% 126.05/16.56  Axiom 4 (cls_typing_OApp_0): fresh131(X, X, Y, Z, W, V) = true2.
% 126.05/16.56  Axiom 5 (cls_lift__type_0): fresh242(X, X, Y, Z, W, V, U) = true2.
% 126.05/16.56  Axiom 6 (cls_typing_OApp_0): fresh132(X, X, Y, Z, W, V, U) = c_Type_Otyping(Y, hAPP(hAPP(c_Lambda_OdB_OApp, Z), W), V).
% 126.05/16.56  Axiom 7 (cls_lift__type_0): fresh242(c_Type_Otyping(X, Y, Z), true2, X, W, V, Y, Z) = c_Type_Otyping(c_Type_Oshift(X, W, V, tc_Type_Otype), c_Lambda_Olift(Y, W), Z).
% 126.05/16.56  Axiom 8 (cls_typing_OApp_0): fresh132(c_Type_Otyping(X, Y, Z), true2, X, W, Y, V, Z) = fresh131(c_Type_Otyping(X, W, hAPP(hAPP(c_Type_Otype_OFun, Z), V)), true2, X, W, Y, V).
% 126.05/16.56  
% 126.05/16.56  Goal 1 (cls_conjecture_0): c_Type_Otyping(c_Type_Oshift(v_ea____, c_HOL_Ozero__class_Ozero(tc_nat), hAPP(hAPP(c_Type_Otype_OFun, v_Ta____), v_U____), tc_Type_Otype), hAPP(hAPP(c_Lambda_OdB_OApp, c_Lambda_OdB_OVar(c_HOL_Ozero__class_Ozero(tc_nat))), c_Lambda_Olift(v_ta____, c_HOL_Ozero__class_Ozero(tc_nat))), v_U____) = true2.
