WebDefinition. Operator A satisfying (∗) is called Hilbert-Schmidt. The class of such operators is denoted by S 2 and we introduce kAk S 2 = X j kAe jk2 1/2. Remark 1. Any operator of finite rank is Hilbert-Schmidt. Remark 2. kAk S 2 introduced above satisfies all requirements of being a norm. 1 WebJul 19, 2024 · $\begingroup$ But for rank $1$ operators, trace norm and operator norm are equal, so the sum is convergent for the trace norm. $\endgroup$ – Mikael de la Salle. ... since trace class is a strictly stronger property than Hilbert-Schmidt.
