A Naïve Introduction to Trans-Elliptic Diophantine Equations Linear Diophantine Equation : Solve $2x + 3y = 5$
3. Methods and tools
- GCD and modular arithmetic: Basic existence checks and impossibility proofs via residues.
- Euclidean algorithm: To find particular solutions for linear equations.
- Infinite descent: Proof technique used by Fermat and others to show impossibility or finiteness.
- Continued fractions: Central to solving Pell’s equation and approximating irrationals.
- Algebraic number theory: Ideals and units in number fields handle higher-degree equations.
- Elliptic curves: Many cubic Diophantine equations reduce to studying rational points on elliptic curves; Mordell’s theorem states rational points form a finitely generated abelian group.
- Baker’s theory: Linear forms in logarithms give explicit bounds for exponential Diophantine equations.
- Computational methods: LLL lattice reduction, modular techniques, descent algorithms, and computer algebra systems.
