Synergies: The following modules go well together with Elliptic Curves:
Content: We hope to cover the following topics in varying levels of detail:
- Non-singular cubics and the group law; Weierstrass equations
- Elliptic curves over the rationals; descent, bounding , heights and the Mordell-Weil theorem, torsion groups; the Nagell-Lutz theorem
- Elliptic curves over complex numbers, elliptic functions
- Elliptic curves over finite fields; Hasse estimate, application to public key cryptography
- Application to diophantin equations: elliptic diophantine problems, Fermat's Last Theorem
- Application to integer factorisation: Pollard's $ p-1 $ method and the elliptic curve method
Leads to: Ph.D. studies in number theory or algebraic geometry.
