Szilard Szabo:
The oper stratification and apparent singularities
Kivonat: After a short discussion of the Hodge moduli space of
a complex projective curve, we describe a recent
construction of C. Simpson for holomorphic connections
on complex projective curves, which leads to a stratification
of the de Rham moduli space. Then we discuss the extension
of these results to quasi-projective curves with parabolic
structure. Finally, we sketch a conjectural link to
apparent singularities of differential equations.
