Imaginary powers and Interpolation spaces of unbounded operators
Summary: We show that there exists an operator \(A\) of type \((0,2)\) with domain \(D(A)\) on the Hilbert space \(L^2\), such that \(A^{is}\) is bounded for each \(s\in\mathbb{R}\) and that for every \(0<\theta<1\), we have \((D(A), L^2)_\theta\neq (D(A^*), L^2)_\theta\).
