ERRATUM

In my paper “The Riemann–Hilbert Problem for a Holomorphic Vector,” published in DAN, vol. 126, no. 4, 1959, in the definition of the class of quasi-diagonal matrices (\Lambda), a series of “elementary cells” of the form

[
\left(
\begin{array}{cc}
z^{\chi_1}, & iz^{\chi_2}\psi_k(z)\
0, & z^{\chi_2}
\end{array}
\right),
\qquad
\text{where }\psi_k(z)=\frac{1+z-2z^{k+1}}{1-z}
\quad (D \text{ is the disk } |z|<1),
]

was omitted, where (\chi_1) and (\chi_2) are the partial indices of the cell, (k=\chi_1-\chi_2-1>0). In connection with this, the corollary to Theorem 1 is incorrect, and the formula for (l(A)) takes the form

[
l=\sum_i (2|\chi_{r_i}|+1)+\sum_j 2|\chi_{\rho_j}|,
]

where (\chi_{r_i}) are all free partial indices, (\chi_{r_i}\leqslant 0), or those coupled indices ((\chi_{r_i},\chi_{r_i+1})) for which (\chi_{r_i}\leqslant 0,\ \chi_{r_i+1}<0), and (\chi_{\rho_j}) are the remaining negative partial indices. Theorem 1 is valid if (\Lambda) is understood in the indicated extended sense. The remaining theorems remain unchanged.
