Correction

In my article “General boundary value problem for second-order elliptic systems with constant coefficients,” published in vol. 2, no. 1, after the colon in the next-to-last line of page 3 through the end of the paragraph on page 4, instead of the text printed there, it should read:

“The rank of the matrix

\[ \int_{\gamma} \bigl(a(z)+\lambda b(z)\bigr)\,\Delta(z,\lambda)\,X(\lambda)\,d\lambda,\qquad z\in\Gamma, \tag{4} \]

is equal to \(n\), where \(X(\lambda)=(E,\lambda E)\); \(E\) is the identity matrix of order \(n\); \(\Delta(z,\lambda)\) is the inverse of the matrix \(A+2B\lambda+C\lambda^{2}\); \(\gamma\) is a contour in the half-plane \(\operatorname{Im}\lambda>0\) enclosing all the roots of the polynomial \(\det(A+2B\lambda+C\lambda^{2})\) that lie in this half-plane.”
