Description

This book is devoted to Hilbert's 21st problem (the Riemann-Hilbert problem) which belongs to the theory of linear systems of ordinary differential equations in the complex domain.

The problem concems the existence of a Fuchsian system with prescribed singularities and monodromy.

Hilbert was convinced that such a system always exists.

However, this tumed out to be a rare case of a wrong forecast made by hirn.

In 1989 the second author (A.B.) discovered a counterexample, thus 1 obtaining a negative solution to Hilbert's 21st problem.

After we recognized that some "data" (singularities and monodromy) can be obtai- ned from a Fuchsian system and some others cannot, we are enforced to change our point of view.

To make the terminology more precise, we shaII caII the foIIowing problem the Riemann-Hilbert problem for such and such data: does there exist a Fuchsian system having these singularities and monodromy?

The contemporary version of the 21 st Hilbert problem is to find conditions implying a positive or negative solution to the Riemann-Hilbert problem.
