% 0.20/0.52  original problem:
% 0.20/0.52  axioms:
% 0.20/0.52  c_UNITY_OInit(v_F(), t_a()) = c_UNITY_OInit(v_G(), t_a())
% 0.20/0.52  c_UNITY_OActs(v_F(), t_a()) = c_UNITY_OActs(v_G(), t_a())
% 0.20/0.52  c_UNITY_OAllowedActs(v_F(), t_a()) = c_UNITY_OAllowedActs(v_G(), t_a())
% 0.20/0.52  c_UNITY_Omk__program(c_Pair(c_UNITY_OInit(V_y, T_a), c_Pair(c_UNITY_OActs(V_y, T_a), c_UNITY_OAllowedActs(V_y, T_a), tc_set(tc_set(tc_prod(T_a, T_a))), tc_set(tc_set(tc_prod(T_a, T_a)))), tc_set(T_a), tc_prod(tc_set(tc_set(tc_prod(T_a, T_a))), tc_set(tc_set(tc_prod(T_a, T_a))))), T_a) = V_y
% 0.20/0.52  goal:
% 0.20/0.52  v_F() != v_G()
% 0.20/0.52  To show the unsatisfiability of the original goal,
% 0.20/0.52  it suffices to show that v_F() = v_G() (skolemized goal) is valid under the axioms.
% 0.20/0.52  Here is an equational proof:
% 0.20/0.52  0: c_UNITY_OInit(v_F(), t_a()) = c_UNITY_OInit(v_G(), t_a()).
% 0.20/0.52  Proof: Axiom.
% 0.20/0.52  
% 0.20/0.52  1: c_UNITY_OActs(v_F(), t_a()) = c_UNITY_OActs(v_G(), t_a()).
% 0.20/0.52  Proof: Axiom.
% 0.20/0.52  
% 0.20/0.52  2: c_UNITY_OAllowedActs(v_F(), t_a()) = c_UNITY_OAllowedActs(v_G(), t_a()).
% 0.20/0.52  Proof: Axiom.
% 0.20/0.52  
% 0.20/0.52  3: c_UNITY_Omk__program(c_Pair(c_UNITY_OInit(X0, X1), c_Pair(c_UNITY_OActs(X0, X1), c_UNITY_OAllowedActs(X0, X1), tc_set(tc_set(tc_prod(X1, X1))), tc_set(tc_set(tc_prod(X1, X1)))), tc_set(X1), tc_prod(tc_set(tc_set(tc_prod(X1, X1))), tc_set(tc_set(tc_prod(X1, X1))))), X1) = X0.
% 0.20/0.52  Proof: Axiom.
% 0.20/0.52  
% 0.20/0.52  6: v_G() = c_UNITY_Omk__program(c_Pair(c_UNITY_OInit(v_G(), t_a()), c_Pair(c_UNITY_OActs(v_G(), t_a()), c_UNITY_OAllowedActs(v_F(), t_a()), tc_set(tc_set(tc_prod(t_a(), t_a()))), tc_set(tc_set(tc_prod(t_a(), t_a())))), tc_set(t_a()), tc_prod(tc_set(tc_set(tc_prod(t_a(), t_a()))), tc_set(tc_set(tc_prod(t_a(), t_a()))))), t_a()).
% 0.20/0.52  Proof: A critical pair between equations 3 and 2.
% 0.20/0.52  
% 0.20/0.52  7: v_G() = v_F().
% 0.20/0.52  Proof: Rewrite equation 6,
% 0.20/0.52                 lhs with equations []
% 0.20/0.52                 rhs with equations [0,1,3].
% 0.20/0.52  
% 0.20/0.52  8: v_F() = v_G().
% 0.20/0.52  Proof: Rewrite lhs with equations []
% 0.20/0.52                 rhs with equations [7].
