Abstract:
The solvability of the Riemann–Hilbert problem for representations χ=χ1⊕χ2 having the form of a direct sum is considered. It is proved that any representation χ1 can be realized as a direct summand in the monodromy representation χ of a Fuchsian system. Other results are also obtained, which suggest a simple method for constructing counterexamples to the Riemann–Hilbert problem.
