WebJul 11, 2024 · Following the wikipedia article one can construct the tensor product of Hilbert spaces H 1 and H 2 as the space which is isometrically and linearly isomorphic to H S ( H 1 ∗, H 2), the space of Hilber-Schmidt operators from H 1 ∗ to H 2. The idea is to identify to every tensor x 1 ⊗ x 2 with x i ∈ H i and x ∗ ∈ H 1 ∗ the map x ∗ ↦ x ∗ ( x 1) x 2
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.
