摘要
Spectral properties of singular Sturm-Liouville operators of the form A = sgn(.) (-d(2)/dx(2) + V) with the indefinite weight z -> sgn(x) on R are studied. For a class of potentials with lim(vertical bar x vertical bar ->infinity) V(x) = 0 the accumulation of complex and real eigenvalues of A to zero is investigated and explicit eigenvalue problems are solved numerically.
