WebIn mathematics, a norm is a function from a real or complex vector space to the non-negative real numbers that behaves in certain ways like the distance from the origin: it commutes with scaling, obeys a form of the triangle inequality, and is zero only at the origin.In particular, the Euclidean distance in a Euclidean space is defined by a norm on … Webof the NP operators belongs to a certain Schatten class. We then use the Weyl’s lemma, which asserts the ℓp-norm of eigenvalues is less than that of singular values, to derive decay rates of eigenvalues.
