On modules of eigenvalues for non-selfadjoint Agmon-Douglis-Nirenberg elliptic boundary problems with a parameter
The author presents some extensions of his previous results concerning the theory of matrix Douglis-Nirenberg elliptic operators and also the operators polynomially depending on a spectral parameter [Funct. Anal. Appl. 21, 53-56 (1987); translation from Funkts. Anal. Prilozh. 21, No. 1, 63-65 (1987; Zbl 0631.35074)] to the case of compact manifolds with boundary.
