Sturm-Liouville operator equation with selfadjoint operator coefficent has been studied in detail. In this paper, we consider the Sturm-Liouville operator equation with non-selfadjoint operator coefficent. Namely, we examine the non-selfadjoint SturmLiouville operator L which is generated in L-2 (R+, H) by the differential expression
