% 5.40/5.50 % SZS status Unsatisfiable
% 5.40/5.50 % SZS output start Proof
% 5.40/5.50 The input problem is unsatisfiable because
% 5.40/5.50
% 5.40/5.50 [1] the following set of Horn clauses is unsatisfiable:
% 5.40/5.50
% 5.40/5.50 implies(truth, X) = X
% 5.40/5.50 implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 5.40/5.50 implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 5.40/5.50 implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 5.40/5.50 not(not(x)) = x ==> \bottom
% 5.40/5.50
% 5.40/5.50 This holds because
% 5.40/5.50
% 5.40/5.50 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 5.40/5.50
% 5.40/5.50 E:
% 5.40/5.50 f1(not(not(x))) = true__
% 5.40/5.50 f1(x) = false__
% 5.40/5.50 implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 5.40/5.50 implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 5.40/5.50 implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 5.40/5.50 implies(truth, X) = X
% 5.40/5.50 G:
% 5.40/5.50 true__ = false__
% 5.40/5.50
% 5.40/5.50 This holds because
% 5.40/5.50
% 5.40/5.50 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 5.40/5.50
% 5.40/5.50 implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 5.40/5.50 implies(implies(X0, X0), truth) = implies(implies(X0, truth), implies(X0, truth))
