WebWe remind the reader that the positive integral operator on the right hand side of equation (2.7) is the renowned Birman-Schwinger operator, widely used in the literature on small pertur-bations of the Laplacian in the sense of quadratic forms, and that the two integral operators are isospectral (see [13], [14]).

Since in our case the initial domain of B ∗ is C 0 ∞ (R n; ℂ N), hence dense in ℌ, we get that K z is exactly the closure of A (H 0 − z) − 1 B ∗. fit2work badgeWebself-adjoint operators.
