% 1.43/1.65 % SZS output start Proof
% 1.43/1.65 The input problem is unsatisfiable because
% 1.43/1.65
% 1.43/1.65 [1] the following set of Horn clauses is unsatisfiable:
% 1.43/1.65
% 1.43/1.65 multiply(identity, X) = X
% 1.43/1.65 multiply(inverse(X), X) = identity
% 1.43/1.65 multiply(multiply(X, Y), Z) = multiply(X, multiply(Y, Z))
% 1.43/1.65 greatest_lower_bound(X, Y) = greatest_lower_bound(Y, X)
% 1.43/1.65 least_upper_bound(X, Y) = least_upper_bound(Y, X)
% 1.43/1.65 greatest_lower_bound(X, greatest_lower_bound(Y, Z)) = greatest_lower_bound(greatest_lower_bound(X, Y), Z)
% 1.43/1.65 least_upper_bound(X, least_upper_bound(Y, Z)) = least_upper_bound(least_upper_bound(X, Y), Z)
% 1.43/1.65 least_upper_bound(X, X) = X
% 1.43/1.65 greatest_lower_bound(X, X) = X
% 1.43/1.65 least_upper_bound(X, greatest_lower_bound(X, Y)) = X
% 1.43/1.65 greatest_lower_bound(X, least_upper_bound(X, Y)) = X
% 1.43/1.65 multiply(X, least_upper_bound(Y, Z)) = least_upper_bound(multiply(X, Y), multiply(X, Z))
% 1.43/1.65 multiply(X, greatest_lower_bound(Y, Z)) = greatest_lower_bound(multiply(X, Y), multiply(X, Z))
% 1.43/1.65 multiply(least_upper_bound(Y, Z), X) = least_upper_bound(multiply(Y, X), multiply(Z, X))
% 1.43/1.65 multiply(greatest_lower_bound(Y, Z), X) = greatest_lower_bound(multiply(Y, X), multiply(Z, X))
% 1.43/1.65 least_upper_bound(a, b) = b
% 1.43/1.65 least_upper_bound(b, c) = c
% 1.43/1.65 least_upper_bound(a, c) = c ==> \bottom
% 1.43/1.65
% 1.43/1.65 This holds because

% 1.43/1.65 least_upper_bound(b, c) = c
