  3. Such set is called an empty set and denoted by 0.

    none of those sound right, but it's because of the first part. Such a set is called an empty set and is denoted by 0. sounds best to me.

    All the sentences are equally ungrammatical, because Such requires an indefinite article before set; i.e, they should all start Such a set. As for the other differences, that's just normal Conjunction Reduction; all are grammatical if the subject is changed. Dec 22, 2014 at 23:09
  • just as a note, rather than using an indefinite article, you could make set plural as long as the verbs agree: Such sets are called empty sets and are denoted by 0. plurality is not needed for conveying the intended meaning (and i would not write the sentence this way), but it is "correct" english as well.

    Correct 'english' is 'English'. Dec 22, 2014 at 23:22
  • This question appears to be off-topic because it is based on the false assumption that at least one of the choices presented is correct, when in fact not one of them is.

While the rest of them quibble, I will summarize: #2 is best, but you need to insert "a" — "Such a set". Clear?
