Here the \( f_i \in k[X_1 ,...,X_n ] \) are polynomials in n variables with coefficients in a field k. The set of solutions is a subset \( V(f_1 ,...,f_r ) \) of \( k^n \). Polynomial equations are omnipresent in and outside mathematics, and have been studied since antiquity. The focus of algebraic geometry is studying the geometric structure of their solution sets.
