Elliptic curves and arithmetic geometry

Connect cubic curves to group laws, rational points, isogenies, local reduction, and arithmetic evidence.

  1. 01

    Weierstrass models and nonsingular cubics

    Identify the smooth projective curve behind a cubic equation and distinguish an elliptic curve from a singular drawing.

    34 min
  2. 02

    The chord–tangent group law

    Compute sums on a smooth cubic while separating rational formulas from the proof of associativity.

    35 min
  3. 03

    Rational functions, divisors and differentials

    Track zeros and poles with local parameters and recover the group law through degree-zero divisor classes.

    38 min
  4. 04

    Isogenies and torsion subgroups

    Relate finite morphisms, function-field degree and geometric kernels without confusing separable and inseparable behavior.

    39 min
  5. 05

    Reduction modulo primes and Hasse's bound

    Count points on a smooth finite-field reduction and distinguish singular equations, local models and intrinsic bad reduction.

    38 min
  6. 06

    Formal groups and local points

    Describe points near infinity with a single p-adic parameter and connect reduction kernels to a convergent formal group law.

    39 min
  7. 07

    Heights and the Mordell–Weil theorem

    Use arithmetic size, quadratic normalization and descent to explain finite generation over a number field.

    41 min
  8. 08

    Descent and Selmer groups

    Use local conditions to bound rational-point rank while keeping the remaining Tate–Shafarevich obstruction explicit.

    41 min
  9. 09

    Complex uniformization and lattices

    Build a complex elliptic curve from a rank-two lattice and interpret complex-linear maps through their lattice indices.

    40 min
  10. 10

    L-functions and the Birch–Swinnerton-Dyer conjecture

    Build the rational elliptic L-function from local counts and state exactly which links to rational rank remain conjectural.
