% 2.22/2.36 % SZS status Unsatisfiable
% 2.22/2.36 % SZS output start Proof
% 2.22/2.36 The input problem is unsatisfiable because
% 2.22/2.36
% 2.22/2.36 [1] the following set of Horn clauses is unsatisfiable:
% 2.22/2.36
% 2.22/2.36 multiply(add(X, Y), Y) = Y
% 2.22/2.36 multiply(X, add(Y, Z)) = add(multiply(Y, X), multiply(Z, X))
% 2.22/2.36 add(X, inverse(X)) = n1
% 2.22/2.36 add(multiply(X, Y), Y) = Y
% 2.22/2.36 add(X, multiply(Y, Z)) = multiply(add(Y, X), add(Z, X))
% 2.22/2.36 multiply(X, inverse(X)) = n0
% 2.22/2.36 multiply(b, a) = multiply(a, b) ==> \bottom
% 2.22/2.36
% 2.22/2.36 This holds because
% 2.22/2.36
% 2.22/2.36 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 2.22/2.36
% 2.22/2.36 E:
% 2.22/2.36 add(X, inverse(X)) = n1
% 2.22/2.36 add(X, multiply(Y, Z)) = multiply(add(Y, X), add(Z, X))
% 2.22/2.36 add(multiply(X, Y), Y) = Y
% 2.22/2.36 f1(multiply(a, b)) = false__
% 2.22/2.36 f1(multiply(b, a)) = true__
% 2.22/2.36 multiply(X, add(Y, Z)) = add(multiply(Y, X), multiply(Z, X))
% 2.22/2.36 multiply(X, inverse(X)) = n0
% 2.22/2.36 multiply(add(X, Y), Y) = Y
% 2.22/2.36 G:
% 2.22/2.36 true__ = false__
% 2.22/2.36
% 2.22/2.36 This holds because
% 2.22/2.36
% 2.22/2.36 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 2.22/2.36
% 2.22/2.36 add(inverse(n1), Y1) = add(Y1, inverse(n1))
% 2.22/2.36 add(inverse(n1), multiply(Y2, inverse(Y0))) = multiply(inverse(Y0), add(Y0, Y2))
% 2.22/2.36 add(multiply(Y0, inverse(Y2)), inverse(n1)) = multiply(inverse(Y2), add(Y0, Y2))
% 2.22/2.36 multiply(X, add(Y, Z)) = add(multiply(Y, X), multiply(Z, X))
% 2.22/2.36 multiply(Y0, Y2) = multiply(Y2, Y0)
% 2.22/2.36 multiply(Y0, n1) = add(multiply(Y1, Y0), multiply(inverse(Y1), Y0))

% 2.22/2.36 add(multiply(false__, inverse(n1)), multiply(inverse(false__), inverse(n1))) -> inverse(n1)
% 2.22/2.36 add(n1, inverse(Y0)) -> n1
% 2.22/2.36 add(n1, multiply(inverse(n1), Y1)) -> add(Y1, n1)
