% 1.82/1.96  % SZS status Unsatisfiable
% 1.82/1.96  % SZS output start Proof
% 1.82/1.96  The input problem is unsatisfiable because
% 1.82/1.96  
% 1.82/1.96  [1] the following set of Horn clauses is unsatisfiable:
% 1.82/1.96  
% 1.82/1.96  	multiply(multiply(X, Y), Z) = multiply(X, multiply(Y, Z))
% 1.82/1.96  	multiply(identity, X) = X
% 1.82/1.96  	multiply(inverse(X), X) = identity
% 1.82/1.96  	multiply(b, c) = multiply(d, c)
% 1.82/1.96  	b = d ==> \bottom
% 1.82/1.96  
% 1.82/1.96  This holds because
% 1.82/1.96  
% 1.82/1.96  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 1.82/1.96  
% 1.82/1.96  E:
% 1.82/1.96  	f1(b) = true__
% 1.82/1.96  	f1(d) = false__
% 1.82/1.96  	multiply(b, c) = multiply(d, c)
% 1.82/1.96  	multiply(identity, X) = X
% 1.82/1.96  	multiply(inverse(X), X) = identity
% 1.82/1.96  	multiply(multiply(X, Y), Z) = multiply(X, multiply(Y, Z))
% 1.82/1.96  G:
% 1.82/1.96  	true__ = false__
% 1.82/1.96  
% 1.82/1.96  This holds because
% 1.82/1.96  
% 1.82/1.96  [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 1.82/1.96  
% 1.82/1.96  	multiply(inverse(X1), Y0) = inverse(multiply(inverse(Y0), X1))
% 1.82/1.96  	multiply(inverse(X1), inverse(X0)) = inverse(multiply(X0, X1))
% 1.82/1.96  	d -> b
% 1.82/1.96  	f1(b) -> true__
% 1.82/1.96  	f1(d) -> false__
% 1.82/1.96  	inverse(identity) -> identity
% 1.82/1.96  	inverse(inverse(Y0)) -> Y0
% 1.82/1.96  	inverse(multiply(X1, inverse(multiply(Y0, X1)))) -> Y0
% 1.82/1.97  	multiply(X0, multiply(inverse(X0), Y1)) -> Y1
% 1.82/1.97  	multiply(X1, inverse(multiply(Y1, X1))) -> inverse(Y1)
% 1.82/1.97  	multiply(X1, inverse(multiply(inverse(Y0), X1))) -> Y0
% 1.82/1.97  	multiply(Y0, inverse(Y0)) -> identity
% 1.82/1.97  	multiply(Y0, multiply(Y1, inverse(multiply(Y0, Y1)))) -> identity
% 1.82/1.97  	multiply(Y0, multiply(Y1, multiply(inverse(multiply(Y0, Y1)), X1))) -> X1
% 1.82/1.97  	multiply(Y1, identity) -> Y1
% 1.82/1.97  	multiply(b, c) -> inverse(multiply(inverse(c), inverse(b)))
% 1.82/1.97  	multiply(identity, X) -> X
% 1.82/1.97  	multiply(inverse(X), X) -> identity
% 1.82/1.97  	multiply(inverse(Y1), multiply(Y1, Y2)) -> Y2
% 1.82/1.97  	multiply(inverse(multiply(X0, X1)), X0) -> inverse(X1)
% 1.82/1.97  	multiply(inverse(multiply(X0, X1)), multiply(X0, multiply(X1, Y1))) -> Y1
% 1.82/1.97  	multiply(multiply(X, Y), Z) -> multiply(X, multiply(Y, Z))
% 1.82/1.97  	true__ -> false__
% 1.82/1.97  with the LPO induced by
% 1.82/1.97  	multiply > identity > d > b > c > inverse > f1 > true__ > false__
% 1.82/1.97  
% 1.82/1.97  % SZS output end Proof
