Polynomial equations

Definition

Polynomial equations are mathematical expressions that involve variables raised to non-negative integer powers, combined with coefficients, and equated to zero. They serve as the foundation for many problems in computational algebraic geometry, particularly in areas like computer vision and robot kinematics, where solutions often require finding the intersections of geometric objects or solving for motion parameters.
