complex algebraic variety

A complex algebraic variety is a geometric object defined by solving polynomial equations with complex number coefficients. Think of it as a shape or space built from the solutions to these equations, which can be points, curves, surfaces, or higher-dimensional analogs. These varieties encode rich geometric and algebraic information, connecting how polynomials behave with the shapes they form in complex number space. They are fundamental in advanced areas of mathematics because they help us understand complex geometric structures through algebraic equations.
