% 0.16/0.49 % SZS output start Proof
% 0.16/0.49 Take the following subset of the input axioms:
% 0.16/0.49 fof(additive_associativity, axiom, ![A, B, C]: addition(A, addition(B, C))=addition(addition(A, B), C)).
% 0.16/0.49 fof(additive_commutativity, axiom, ![A2, B2]: addition(A2, B2)=addition(B2, A2)).
% 0.16/0.49 fof(additive_idempotence, axiom, ![A2]: addition(A2, A2)=A2).
% 0.16/0.49 fof(additive_identity, axiom, ![A2]: addition(A2, zero)=A2).
% 0.16/0.49 fof(domain1, axiom, ![X0]: addition(X0, multiplication(domain(X0), X0))=multiplication(domain(X0), X0)).
% 0.16/0.49 fof(domain2, axiom, ![X1, X0_2]: domain(multiplication(X0_2, X1))=domain(multiplication(X0_2, domain(X1)))).
% 0.16/0.49 fof(domain3, axiom, ![X0_2]: addition(domain(X0_2), one)=one).
% 0.16/0.49 fof(domain4, axiom, domain(zero)=zero).
% 0.16/0.49 fof(goals, conjecture, ![X0_2]: (![X1_2]: (addition(domain(X1_2), antidomain(X1_2))=one & multiplication(domain(X1_2), antidomain(X1_2))=zero) => domain(antidomain(X0_2))=antidomain(X0_2))).
% 0.16/0.49 fof(left_annihilation, axiom, ![A2]: multiplication(zero, A2)=zero).
% 0.16/0.49 fof(left_distributivity, axiom, ![A2, B2, C2]: multiplication(addition(A2, B2), C2)=addition(multiplication(A2, C2), multiplication(B2, C2))).
% 0.16/0.49 fof(multiplicative_left_identity, axiom, ![A2]: multiplication(one, A2)=A2).
% 0.16/0.49 fof(multiplicative_right_identity, axiom, ![A2]: multiplication(A2, one)=A2).
% 0.16/0.49 fof(right_distributivity, axiom, ![A2, B2, C2]: multiplication(A2, addition(B2, C2))=addition(multiplication(A2, B2), multiplication(A2, C2))).
% 0.16/0.49
% 0.16/0.49 Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.16/0.49 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.16/0.49 We repeatedly replace C & s=t => u=v by the two clauses:
% 0.16/0.49 fresh(y, y, x1...xn) = u
% 0.16/0.49 C => fresh(s, t, x1...xn) = v
% 0.16/0.49 where fresh is a fresh function symbol and x1..xn are the free
% 0.16/0.49 variables of u and v.
% 0.16/0.49 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.16/0.49 input problem has no model of domain size 1).
% 0.16/0.49
% 0.16/0.49 The encoding turns the above axioms into the following unit equations and goals:
% 0.16/0.49
% 0.16/0.49 Axiom 1 (domain4): domain(zero) = zero.
% 0.16/0.49 Axiom 2 (additive_idempotence): addition(X, X) = X.
% 0.16/0.49 Axiom 3 (additive_commutativity): addition(X, Y) = addition(Y, X).
% 0.16/0.49 Axiom 4 (additive_identity): addition(X, zero) = X.
% 0.16/0.49 Axiom 5 (multiplicative_right_identity): multiplication(X, one) = X.
% 0.16/0.49 Axiom 6 (left_annihilation): multiplication(zero, X) = zero.
% 0.16/0.49 Axiom 7 (multiplicative_left_identity): multiplication(one, X) = X.
% 0.16/0.49 Axiom 8 (domain3): addition(domain(X), one) = one.
% 0.16/0.49 Axiom 9 (goals): addition(domain(X), antidomain(X)) = one.
% 0.16/0.49 Axiom 10 (additive_associativity): addition(X, addition(Y, Z)) = addition(addition(X, Y), Z).
% 0.16/0.49 Axiom 11 (goals_1): multiplication(domain(X), antidomain(X)) = zero.
% 0.16/0.49 Axiom 12 (domain2): domain(multiplication(X, Y)) = domain(multiplication(X, domain(Y))).
% 0.16/0.49 Axiom 13 (domain1): addition(X, multiplication(domain(X), X)) = multiplication(domain(X), X).
% 0.16/0.49 Axiom 14 (right_distributivity): multiplication(X, addition(Y, Z)) = addition(multiplication(X, Y), multiplication(X, Z)).
% 0.16/0.49 Axiom 15 (left_distributivity): multiplication(addition(X, Y), Z) = addition(multiplication(X, Z), multiplication(Y, Z)).
% 0.16/0.49
% 0.16/0.49 Lemma 16: addition(one, domain(X)) = one.
