A selfadjoint differential operator defined over a closed and bounded interval on Sobolev space which is a dense linear subspace of a Hilbert space over the same interval is considered and shown to be a Fredholm operator with index zero.
KEY WORDS: Sobolev space, Hilbert space, dense subspace, Fredholm operator
