Higher-Order-Schmidt-Representations and their Relevance for the Basis-Ambiguity

Abstract

With the help of a useful mathematical tool, the polar decomposition of closed operators, and a simple observation, i.e. the unique relation between tensor-product states and compact operators, we manage to give a compact and coherent account of the various properties of higher-order-Schmidt-representations.
