Erratum to the paper: “Elliptic differential-operator problems with a spectral parameter in both the equation and boundary-operator conditions” [Adv. Differ. Equ. 11, No. 10, 1081–1110 (2006)]. (English) Zbl 1200.34063

From the text: A part of the proof of Theorem 1 after formula (2.6) should be changed in accordance with page 288 in [S. Yakubov and Y. Yakubov, Differential-operator equations: ordinary and partial differential equations., Chapman & Hall/CRC Monographs and Surveys in Pure and Applied Mathematics. 103. Boca Raton, FL: Chapman & Hall/CRC., (2000; Zbl 0936.35002)]. Then, one has to change \(\frac{1}{2}m_k\) to \(m_k\) in estimates of all theorems.
