In particular, we consider that the minimal symmetric operator generated by the third-order differential expression has the deficiency indices (3,3). We investigate same spectral properties related with these problems, and we introduce a method to find the resolvent operator.eninfo:eu-repo/semantics/closedAccessBoundary Value ProblemResolvent OperatorThird-Order EquationArticle10.1002/mma.60342-s2.0-85075741331
