Eintheilung und Bermessung des Revieresh that . = ∑...... This makes it natural to study the relationship between frames and bases. We have already seen that Riesz bases are frames. In this chapter we exploit the relationship between these two concepts further. In particular, we give equivalent conditions for a frame to be a Riesz basis.

Frames in Finite-dimensional Inner Product Spaces,ination of the elements in the basis. However, the conditions to a basis are very restrictive — no linear dependence between the elements is possible and sometimes we even want the elements to be orthogonal with respect to an inner product. This makes it hard or even impossible to find bases satisfy

The relevant conditions were discovered by Janssen, and the main part of this chapter will deal with his results..One can also consi

Bases,ion 3.4 we discuss the most important properties of orthonormal bases in Hilbert spaces; we expect the reader to have some basic knowledge about this subject. A slight (but useful) modification leads to the definition of Riesz bases, which are treated in detail in Section 3.6. Orthonormal bases and
