Self-Adjoint Realization of a Class of Third-Order Differential Operators With an Eigenparameter Contained in the Boundary Conditions

Eigenvalues of a Class of Eigenparameter Dependent Third-Order Differential Operators

“…Proof For detail proof, we refer to [34]. ◻ Let Let 1 (x, ), 2 (x, ), 3 (x, ) be the system of linearly independent fundamental solutions of Eq.…”
