WebThe Hilbert-Schmidt operators form an ideal of the set of bounded operators. An interest of the Hilbert-Schmidt operators is that it can be endowed with an inner product, defining S, T H S := ∑ j = 1 + ∞ S e n, T e n . It can be shown with Bessel's equality that this doesn't depend on the choice of the Hilbert basis. WebDifferentiability in the Hilbert–Schmidt norm Suppose that A and B are not necessarily bounded self-adjoint operators on Hilbert space such that A − B ∈ S 2 .

HILBERT-SCHMIDT AND TRACE CLASS OPERATORS

WebThe Hilbert-Schmidt operators include such operators, where the integral kernel K(x;y) is allowed to be in L2 [a;b] [a;b]. [1.2] Hilbert-Schmidt norm on V alg W In the category of Hilbert spaces and continuous linear maps, there is no tensor product in the categorical sense, as demonstrated in an appendix. WebJul 24, 2024 · If a bounded operator on a separable Hilbert space can be written as the product of two HS operators, then we say that this operator is trace-class. One characterization of such operators is that a bounded operator C is trace-class if and only if C is compact and (C ∗ C)1 / 2 has summable eigenvalues.
