On the spectrum of an operator pencil generated by the Neumann problem in a cone. (Russian) Zbl 0744.35025
The authors describe the spectrum of an operator pencil generated by the Neuman problem for an elliptic system of order \(2m\) in a cone, situated in the strip \(|\hbox{Re} \lambda-m+{n\over 2}|\leq{1\over 2}\).
