I don't know what you mean by "cota problem". Quote:
The Hyperreal numbers are a tool for pursuing a more intuitive approach to real calculus. In particular they do not exist in Real or Complex Analysis. Real calculus using the Hyperreal numbers is called NonStandard Analysis. They are not used more widely because Hyperreal algebra is inconsistent (as far as I am aware).
