Let \"\Delta\" an operator over the Hilbert space \"\mathcal{H}\", we call it bounded<\/em> if there exists a \"t>0\" such that \"||\Delta |\psi \rangle||\leq  t|||\psi \rangle|| \ \ \forall |\psi \rangle \in \mathcal{H}\", with \"|||\psi\rangle||=\sqrt{\langle \psi | \psi \rangle}\". The set of all bounded operators over \"\mathcal{H}\" is denoted by \"\mathcal{B}(\mathcal{H})\". In particular the minimum \"t\" for which the inequality above holds, is called the operator norm<\/em> of \"\Delta\". This norm induces the operator norm topology. <\/em>Such norm is typically too strong for many purposes, a very wide used one is the so called weak operator topology, <\/em>it will be discussed later.
