Painlevé III: A Case Study in the Geometry of Meromorphic Connections (eBook, PDF)

• Format: PDF

Produktbeschreibung

The purpose of this monograph is two-fold: it introduces a conceptual language for the geometrical objects underlying Painlevé equations, and it offers new results on a particular Painlevé III equation of type PIII (D6), called PIII (0, 0, 4, -4), describing its relation to isomonodromic families of vector bundles on P1 with meromorphic connections. This equation is equivalent to the radial sine (or sinh) Gordon equation and, as such, it appears widely in geometry and physics. It is used here as a very concrete and classical illustration of the modern theory of vector bundles with meromorphic connections.

>0 (with or without singularities) are addressed. These provide examples of variations of TERP structures, which are related to tt* geometry and harmonic bundles.

As an application, a new global picture of0 is given.
