A Spectral Problem with an Indefinite Weight for an Elliptic System
Southwest Texas State University, Department of Mathematics
We establish the completeness and the summability in the sense of Abel-Lidskij of the root vectors of a non-selfadjoint elliptic problem with an indefinite weight matrix and the angular distribution of its eigenvalues.
