A spectral problem with an indefinite weight for an elliptic system
Electronic journal of differential equations, Tome 1997 (1997)
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.
