Infinite-dimensional Vector Spaces and Sequences,After the introduction to frames in finite-dimensional vector spaces in Chapter 1, the rest of the book will deal with expansions in infinite-dimensional vector spaces.

Frames in Hilbert Spaces,The main feature of a basis {..}. in a Hilbert space . is that every . ∈ . can be represented as an (infinite) linear combination of the elements .. in the basis:

General Wavelet Frames,The fundamental question in wavelet analysis is what conditions we have to impose on a function . such that a given signal . ∈ ..(ℝ) can be expanded via translated and scaled versions of ., i.e., via functions

Dyadic Wavelet Frames,In this chapter we consider ., i.e., frames for ..(ℝ) of the type {2..(2.. − .)}.. Bases of this type were considered already in Section 3.8, where we also introduced the short notation {..}. and {.....}.. A frame of this type is said to be . by ..
