Elliptic Curves

Definition

Algebraic geometry is a branch of mathematics that studies the solutions of systems of polynomial equations and the geometric structures that arise from them. It combines techniques from both algebra and geometry to analyze geometric objects, such as curves and surfaces, through the lens of algebraic equations. This field plays a crucial role in understanding various mathematical concepts, including those related to number theory and elliptic curves.
