Abstract

We will show that every bounded Bessel sequence can be decomposed into two subsets each of which is an arbitrarily small perturbation of a sequence with a finite orthogonal decomposition. As an application of this result we prove that the weak Feichtinger Conjecture is equivalent to the Feichtinger Conjecture.
