We study the adjointness problem for the closed extensions of a general b-elliplic operator A ∈ x Diffbm (M;E), ν > 0, initially defined as an unbounded operator A: Ccinfin; (M;E) ⊃ xμLb2(M;E) → xμLb2(M;E), μ ∈ ℝ. The case where A is a symmetric semibounded operator is of particular interest, and we give a complete description of the domain of the Friedrichs extension of such an operator.
