A thread state expression is '''inconsistent''' if it's self-contradictory, like "(P AND NOT P)". This means this thread state expression can never be satisfied; it's never true. Note that "((P AND NOT P) OR Q)" is not inconsistent; it simplifies to "Q". | A thread state expression is '''inconsistent''' if it's self-contradictory, like "(P AND NOT P)".

It means any time the former is true, the latter will be true. | One thread state expression may '''imply''' another, as in logic: "(P AND Q)" implies "(P OR R)".
