SUMMARY

Let H be a complex Hilbert space. A linear (possibly not continuous) operator A on H is called hyponormal if D(A) ⊂ D A*, A u ≤ Au for each u ∈ D(A), where D(A) and D(A* ) denote the domains of A and its adjoint A*, respectively. As an application, the authors will consider a large class of Schrödinger's operators -∆ + Q, where the . . .
