We continue with our overview of unconditional bases for Banach spaces. We will first look at unconditional convergence of series in a Banach space, and its relationship with absolute convergence. This will allow us to characterize unconditional bases, and therefore show that certain specific bases (e.g. the summing basis of and the Haar basis in ) are not unconditional.
