Part of the Nonconvex Optimization and Its Applications book series (NOIA, volume 46)


In this book letters x,y, ... are scalars (real numbers) and the letters in bold italics, x, y, ... , stand for column vectors in the n-dimensional Euclidian space n unless explicitly stated otherwise. The i-th component or element of a vector x is denoted by x i . The superscripts usually represent different vectors, for example, x k ,kK where K is a set of indices. In general the columns of an m x n matrix A (or A m×n ) are denoted by a 1,a 2 ⋯,a n , while the rows by A 1, A 2, ..., A m or {A}i, i = 1, ⋯ , m. The entry in row i and column j of a matrix A is denoted by a ij . g(x)is a column vector-valued function with scalar-valued functions g 1 (x), g 2 (x), ... ,g m (x) as its components. In the following chapters, we sometimes write f k ,g k as abbreviations for f (x k ),g(x k ).
