Hitchin Fibration – Learning Roadmap

The Hitchin fibration is one of the central structures in modern geometry. It connects:

This page collects a recommended path to learn the subject, with references.


1. Hitchin's Original Paper

The starting point of the whole subject.

Nigel Hitchin (1987) “Stable bundles and integrable systems”

Introduces:

PDF: https://people.maths.ox.ac.uk/hitchin/hitchin87.pdf

Key ideas to focus on:


2. Spectral Curve Description (BNR)

This explains the spectral correspondence.

Beauville – Narasimhan – Ramanan

“Spectral curves and the generalized theta divisor”

Link: https://math.univ-cotedazur.fr/~beauvill/pubs/bnr.pdf

The main result:

(E, φ) ↔ line bundle on spectral curve

Consequences:


3. Non-abelian Hodge Theory

Carlos Simpson (1992) “Higgs bundles and local systems”

Link: https://www.numdam.org/item/PMIHES_1992__75__5_0.pdf

Explains the correspondence:

Higgs bundles ↕ flat connections ↕ representations of π₁

Important features:


4. Geometry of the Nilpotent Cone

Gérard Laumon

"Un analogue global du cône nilpotent"

Main result:
