Abstract

In this work, we prove that the closure of a symmetric operator L0 which is formed by differential expression (L0y)(x )= −(p(x)y � (x)) � − Q(x)y(x) and with the boundary condition cos α.y(0) + sin α.y � (0) = 0 is self adjoint where α ∈ (−∞, ∞) in the space L2(0, ∞; H ). Furthermore, we investigate some properties of this operator.
