### Erratum to the paper: "Elliptic differential-operator problems with a spectral parameter in both the equation and boundary-operator conditions"

#### Abstract

A part of the proof of Theorem 1 after formula (2.6) should be changed in accordance to page 288 in the book by S. Yakubov and Ya. Yakubov, "Differential-Operator Equations. Ordinary and Partial Differential Equations", Chapman and Hall/CRC, Boca Raton, 2000. Then, one has to change $\frac {m_k}{2}$ to $m_k$ in estimates of all theorems.
