Algebraic Proof

Definition

An algebraic proof is a method of demonstrating the truth of mathematical statements using algebraic manipulations and logical reasoning. It often involves the use of equations and inequalities to validate claims or derive conclusions, relying on properties of numbers and operations to establish relationships between quantities in a formal way. This approach is particularly useful in understanding the structure and properties of mathematical objects, like elliptic curves, where specific algebraic identities and relationships play a critical role.

  • Algebraic proofs can demonstrate the group law on elliptic curves by using geometric interpretations along with algebraic manipulations. The process starts with selecting two points on the curve, determining their intersection with a vertical line, and using these intersections to find a third point. By applying algebra to show that this third point also lies on the curve and satisfies the required properties of closure under addition, we can formally prove that elliptic curves exhibit group-like behavior under this operation.
