    An equality that is true for all members of a specified set is generally called an "identity" (for example x+x=2x is, say, an identity wrt the set of real numbers).

    But do inequalities that are true for all members of a specified set have an established name?
    (An inequality of that kind would be [itex]x^{2}+1\geq{0}[/itex] for real x).
