% 6.02/6.18 % SZS status Unsatisfiable
% 6.02/6.18 % SZS output start Proof
% 6.02/6.18 The input problem is unsatisfiable because
% 6.02/6.18
% 6.02/6.18 [1] the following set of Horn clauses is unsatisfiable:
% 6.02/6.18
% 6.02/6.18 double_divide(inverse(double_divide(double_divide(A, B), inverse(double_divide(A, inverse(C))))), B) = C
% 6.02/6.18 multiply(A, B) = inverse(double_divide(B, A))
% 6.02/6.18 multiply(multiply(inverse(b2), b2), a2) = a2 ==> \bottom
% 6.02/6.18
% 6.02/6.18 This holds because
% 6.02/6.18
% 6.02/6.18 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 6.02/6.18
% 6.02/6.18 E:
% 6.02/6.18 double_divide(inverse(double_divide(double_divide(A, B), inverse(double_divide(A, inverse(C))))), B) = C
% 6.02/6.18 f1(a2) = false__
% 6.02/6.18 f1(multiply(multiply(inverse(b2), b2), a2)) = true__
% 6.02/6.18 multiply(A, B) = inverse(double_divide(B, A))
% 6.02/6.18 G:
% 6.02/6.18 true__ = false__
% 6.02/6.18
% 6.02/6.18 This holds because
% 6.02/6.18
% 6.02/6.18 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
