% 5.34/5.45 % SZS status Unsatisfiable
% 5.34/5.45 % SZS output start Proof
% 5.34/5.45 The input problem is unsatisfiable because
% 5.34/5.45
% 5.34/5.45 [1] the following set of Horn clauses is unsatisfiable:
% 5.34/5.45
% 5.34/5.45 divide(divide(A, inverse(divide(B, divide(A, C)))), C) = B
% 5.34/5.45 multiply(A, B) = divide(A, inverse(B))
% 5.34/5.45 multiply(multiply(a3, b3), c3) = multiply(a3, multiply(b3, c3)) ==> \bottom
% 5.34/5.45
% 5.34/5.45 This holds because
% 5.34/5.45
% 5.34/5.45 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 5.34/5.45
% 5.34/5.45 E:
% 5.34/5.45 divide(divide(A, inverse(divide(B, divide(A, C)))), C) = B
% 5.34/5.45 f1(multiply(a3, multiply(b3, c3))) = false__
% 5.34/5.45 f1(multiply(multiply(a3, b3), c3)) = true__
% 5.34/5.45 multiply(A, B) = divide(A, inverse(B))
% 5.34/5.45 G:
% 5.34/5.45 true__ = false__
% 5.34/5.45
% 5.34/5.45 This holds because
% 5.34/5.45
% 5.34/5.45 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
