内容説明 Divergent processes are at the core of classical and modern mathematical analysis and the careful control and management of these processes are essential. This text is a survey of results， analysis and applications for the study of divergent processes. It covers a broad range of topics including summability， Fourier series， wavelet transform， singular integrals， spectral theory and asymptotics. It should be a useful resource for pure and applied mathematicians working in the areas of functional analysis， singular integrals， variational problems， signal analysis and wavelet analysis.
