Have not vs. Do not have vs. Have no

The negative of 'have' is 'do not have' when 'have' is a principal verb. 'Have not' is the negative of the auxiliary verb 'have'. 'have not' doesn't mean 'do not own'. Rather it is the negative of a present perfect tense such as 'I have not done it'. However, "have + no + noun" means not having that noun at all.
