An affine variety is the set of points in an affine space whose coordinates are the common zeros of a finite set of polynomials. For a set of polynomials [latex]S = \{f_1, \dots, f_k\}[/latex] in a polynomial ring [latex]k[x_1, \dots, x_n][/latex], the corresponding affine variety is [latex]V(S) = \{x \in k^n | f(x) = 0 \text{ for all } f \in S\}[/latex]. It is a central object of study in classical algebraic geometry.
