Quantum Curves and D-Modules

Understand

In this article we continue our study of chiral fermions on a quantum curve.

• This system is embedded in string theory as an I-brane configuration, which consists of D4 and D6-branes intersecting along a holomorphic curve in a complex surface, together with a B-field.
• Mathematically, it is described by a holonomic D-module.
• Here we focus on spectral curves, which play a prominent role in the theory of (quantum) integrable hierarchies.
