Let us consider the differential expression where c is a transmission point and is regular for the differential expression a""(y). We assume that Weyl's limit-circle case holds for the differential expression a""(y) on I. In this paper, using Krein's theorems, we investigate the completeness of the root vectors of a singular dissipative boundary value transmission problem generated by a""(y).
