13 states some of the fundamental properties of frames. As a concept, frames provide an intermediate ground between the two related notions of completeness in a space and an orthonormal basis for a space. Recall that a set offunctions {rPn} is complete in a Hilbert space U if the closure of their span is the whole space U; that is, opan {rPn} = U. It is shown that the statements that a set {rPn} is (a) complete in U, (b) a frame for U, (c) a Riesz basis for 'l"{, and (d) an orthonormal hasis for H are progressively stronger.

Namely, if L is a frame representation operator then (a) L is injective (one-to-one), (b) L(H) is closed, and (c) L' is surjective (onto). To see the injectivity of the map L suppose {¢n} is a frame for H with bounds A and B and that Lh = Lh. Then which implies that h = h. Thus, L is injective. Because L is an injective bounded linear operator whose range L(H) is closed, then L* is onto. ,12 3. 4 .
