J. Vandamme, THE RIEMANN-HILBERT PROBLEM FOR AN UPPER- TRIANGULAR MONODROMY REPRESENTATION OF DIMENSION-5, Comptes rendus de l'Academie des Sciences. Serie I, Mathematique, 326(9), 1998, pp. 1069-1072
We show that any upper-triangular representation of dimension 5 can be
realized as the monodromy representation of some upper-triangular Fuc
hsian system. (C) Academie des Sciences/Elsevier, Paris.
