E. Bairamov et Am. Krall, Dissipative operators generated by the Sturm-Liouville differential expression in the Weyl limit circle case, J MATH ANAL, 254(1), 2001, pp. 178-190
In this paper, using Livsic's theorem, we investigate the problem of comple
teness of the system of eigenfunctions and associated functions of dissipat
ive operators generated by the Sturm-Liouville differential expression on t
he semi-axis in Weyl's limit-circle case. (C) 2001 Academic Press.
