4.1 Introduction

4.1.1 Notational Conventions

We will first provide a brief description of the notational convention used in this chapter.

x ∈ A	means x is an element of the set A
xA	means x is not an element of the set A
R	is the set of all real numbers
R × R	denotes the Cartesian product, i.e., if x, y ∈ R, the ordered pair (x, y) ∈ R × R
Rn	is the n–dimensional real space
·	is an appropriately defined norm
Br	ball of radius r, r > o, and centered at the origin
