On elliptic operator pencils with general boundary conditions
R. Denk, R. Mennicken, L. Volevich
In this paper operator pencils are investigated which depend polynomially on the parameter and act on a manifold with boundary. The operator A is assumed to satisfy…

Boundary value problems for a class of elliptic operator pencils
R. Denk, R. Mennicken, L. Volevich
In this paper operator pencils are studied which act on a manifold with boundary and satisfy the condition of -ellipticity with parameter, a generalization of the not…
