Let f1,…,fr be complex polynomials in the variables x1,…,xn let V be the variety of their common zeros, and let I be the ideal of the polynomial ring \(R=C[x1,…,xn] \) that they generate. Define a homomorphism from the quotient ring \(\overline{R}=R\ x2F\); I to the ring RR of continuous, complex-valued functions on V.
