  annote = {In many-valued logics with the unit interval as the set of
    truth values, from the standard negation and the product (or, more
    generally, from any strict Frank t-norm) all measurable logical
    functions can be derived, provided that also operations with
    countable arity are allowed. The question remained open whether
    there are other t-norms with this property or whether all strict
    t-norms possess this property. We list several families of strict
    t-norms having this property and provide also counterexamples (the
    Hamacher product is one of them).},
