Riemann-Hilbert problems with singularities Bertrand, Florian
Description
The study of analytic discs attached to a totally real submanifold M of $\mathbb C^n$ leads to the consideration of a regular Riemann-Hilbert problem of a special form. Following this approach, Forstneric, and later on Globevnik, characterized the existence and dimension of a family of deformations of a given analytic disc attached to M in terms of certain indices. However, in case M admits some complex tangencies, the indices mentioned above are no longer well-defined and the Forstneric-Globevnik method falls apart. In this talk, I will focus on a class of such singular Riemann-Hilbert problems. We will see that they can be solved by a factorization technique that reduces them to regular Riemann-Hilbert problems with geometric constraints. In particular, we will deduce the existence of stationary type discs attached to finite type hypersurfaces.

The study of analytic discs attached to a totally real submanifold M of $\mathbb C^n$ leads to the consideration
of a regular Riemann-Hilbert problem of a special form. Following this approach, Forstneric, and later on Globevnik,
characterized the existence and dimension of a family of deformations of a given analytic disc attached to M in terms of
certain indices. However, in case M admits some complex tangencies, the indices mentioned above are no longer
well-defined and the Forstneric-Globevnik method falls apart. In this talk, I will focus on a class of such singular
Riemann-Hilbert problems. We will see that they can be solved by a factorization technique that reduces them to regular
Riemann-Hilbert problems with geometric constraints. In particular, we will deduce the existence of stationary type discs
attached to finite type hypersurfaces.
