curso "Abelian varieties in algebraic integrable systems"
Contents: 6 lectures, each one 55 min., given in Spanish with slides in English.
Description of the first 3 lectures.
Lecture 1. Algebraic curves, Abelian varieties, and algebraic integrable systems.
- A first example: The classical Euler top on so(3). Equations of motion, elliptic curve, linearization.
- Abelian varieties: definitions, basic properties, examples. Jacobi varieties (algebraic and analytical description).
- Algebraic integrable systems. Examples. Historical remarks.
- Exercises.
Lecture 2. Algebraic integrable systems and the Painlevé property.
- More properties of Abelian varieties: divisors, linear systems, embedding to projective space.
- The essence of the Kovalevskaya--Painlevé (KP) analysis: Laurent series solutions, Kowalewski exponents, the theorems of
Adler & van Moerbeke and of Yoshida, and their generalizations.
- Geometric interpretation of the KP analysis.
- Examples: the Euler top again, the Clebsch integrable case of the Kirchoff equations.
Lecture 3. Lax representation and spectral curves.
- What really is a Lax representation of an integrable system. Examples.
- The eigenvector map to the Jacobian of the spectral curve S. Linearization of the flow on the Jacobian.
- The problem of separation of variables.
- Spectral curves with an involution and Prym subvarieties of the Jacobian.
- Relation between the Jacobian of S and the complex invariant manifold of the system.
