% 10.64/10.59 % SZS status Unsatisfiable
% 10.64/10.59 % SZS output start Proof
% 10.64/10.59 The input problem is unsatisfiable because
% 10.64/10.59
% 10.64/10.59 [1] the following set of Horn clauses is unsatisfiable:
% 10.64/10.59
% 10.64/10.59 is_a_theorem(implies(X, Y)) & is_a_theorem(X) ==> is_a_theorem(Y)
% 10.64/10.59 is_a_theorem(implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))))
% 10.64/10.59 is_a_theorem(implies(implies(not(X), X), X))
% 10.64/10.59 is_a_theorem(implies(X, implies(not(X), Y)))
% 10.64/10.59 is_a_theorem(implies(x, implies(y, y))) ==> \bottom
% 10.64/10.59
% 10.64/10.59 This holds because
% 10.64/10.59
% 10.64/10.59 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 10.64/10.59
% 10.64/10.59 E:
% 10.64/10.59 f1(true__, Y) = is_a_theorem(Y)
% 10.64/10.59 f2(is_a_theorem(X), X, Y) = true__
% 10.64/10.59 f2(true__, X, Y) = f1(is_a_theorem(implies(X, Y)), Y)
% 10.64/10.59 f3(is_a_theorem(implies(x, implies(y, y)))) = true__
% 10.64/10.59 f3(true__) = false__

% 10.64/10.59 is_a_theorem(implies(implies(not(X), X), X)) = true__
% 10.64/10.59 G:
% 10.64/10.59 true__ = false__
% 10.64/10.59
% 10.64/10.59 This holds because
% 10.64/10.59
% 10.64/10.59 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
