In other words, ||.–.|| < є, where || • || denotes the uniform norm in .(.). Equivaiently, we may say that there exists a sequence (. : n = 1,2,…) of polynomials such that ||.–.||

The set (.) is called an . (or .) on . if . is the complex conjugate of . and . stands for .… . Of course, the definition makes sense only if
