Incomplete Orthogonal Sets
Given a Hilbert space H and a set S of mutually orthogonal vectors in H, we can take the smallest closed linear subspace V of H containing S. Then S will be an orthogonal basis of V; which may of course be smaller than H itself, being an incomplete orthogonal set, or be H, when it is a complete orthogonal set.

Famous quotes containing the words incomplete and/or sets:
“Someone once asked me why women dont gamble as much as men do, and I gave the common-sensical reply that we dont have as much money. That was a true but incomplete answer. In fact, womens total instinct for gambling is satisfied by marriage.”
—Gloria Steinem (b. 1934)
“Whether changes in the sibling relationship during adolescence create long-term rifts that spill over into adulthood depends upon the ability of brothers and sisters to constantly redefine their connection. Siblings either learn to accept one another as independent individuals with their own sets of values and behaviors or cling to the shadow of the brother and sister they once knew.”
—Jane Mersky Leder (20th century)
