WebThe trick to compute its norm in L2 is to consider S = T ∗ T. Then ‖T‖2 = ‖T ∗ T‖. Use that S is compact and self-adjoint, so its norm is equal to its maximal eigenvalue. An … WebAn integral formula for tr K, proven by Duflo for continuous kernels, is generalized for arbitrary trace class kernels. This formula is shown to be equivalent to one involving the factorization of K into a product of Hilbert-Schmidt operators.
