% 17.85/17.91 % SZS status Unsatisfiable
% 17.85/17.91 % SZS output start Proof
% 17.85/17.91 The input problem is unsatisfiable because
% 17.85/17.91
% 17.85/17.91 [1] the following set of Horn clauses is unsatisfiable:
% 17.85/17.91
% 17.85/17.91 double_divide(double_divide(A, double_divide(double_divide(double_divide(B, A), C), double_divide(B, identity))), double_divide(identity, identity)) = C
% 17.85/17.91 multiply(A, B) = double_divide(double_divide(B, A), identity)
% 17.85/17.91 inverse(A) = double_divide(A, identity)
% 17.85/17.91 identity = double_divide(A, inverse(A))
% 17.85/17.91 multiply(identity, a2) = a2 ==> \bottom
% 17.85/17.91
% 17.85/17.91 This holds because
% 17.85/17.91
% 17.85/17.91 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 17.85/17.91
% 17.85/17.91 E:
% 17.85/17.91 double_divide(double_divide(A, double_divide(double_divide(double_divide(B, A), C), double_divide(B, identity))), double_divide(identity, identity)) = C
% 17.85/17.91 f1(a2) = false__
% 17.85/17.91 f1(multiply(identity, a2)) = true__
% 17.85/17.91 identity = double_divide(A, inverse(A))
% 17.85/17.91 inverse(A) = double_divide(A, identity)
% 17.85/17.91 multiply(A, B) = double_divide(double_divide(B, A), identity)
% 17.85/17.91 G:
% 17.85/17.91 true__ = false__
% 17.85/17.91
% 17.85/17.91 This holds because
% 17.85/17.91
% 17.85/17.91 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
