% 0.48/0.70 % SZS status Unsatisfiable
% 0.48/0.70 % SZS output start Proof
% 0.48/0.70 The input problem is unsatisfiable because
% 0.48/0.70
% 0.48/0.70 [1] the following set of Horn clauses is unsatisfiable:
% 0.48/0.70
% 0.48/0.70 divide(divide(A, divide(B, C)), divide(A, B)) = C
% 0.48/0.70 multiply(A, B) = divide(A, divide(divide(C, C), B))
% 0.48/0.70 inverse(A) = divide(divide(B, B), A)
% 0.48/0.70 multiply(multiply(inverse(b2), b2), a2) = a2 ==> \bottom
% 0.48/0.70
% 0.48/0.70 This holds because
% 0.48/0.70
% 0.48/0.70 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 0.48/0.70
% 0.48/0.70 E:
% 0.48/0.70 divide(divide(A, divide(B, C)), divide(A, B)) = C
% 0.48/0.70 f1(a2) = false__
% 0.48/0.70 f1(multiply(multiply(inverse(b2), b2), a2)) = true__
% 0.48/0.70 inverse(A) = divide(divide(B, B), A)
% 0.48/0.70 multiply(A, B) = divide(A, divide(divide(C, C), B))
% 0.48/0.70 G:
% 0.48/0.70 true__ = false__
% 0.48/0.70
% 0.48/0.70 This holds because
% 0.48/0.70
% 0.48/0.70 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 0.48/0.70
% 0.48/0.70 divide(Y0, Y0) = divide(X0, X0)
% 0.48/0.70 multiply(A, B) = divide(A, divide(divide(C, C), B))
