Functions of pairs of unbounded noncommuting self-adjoint operators under perturbation

Aleksei Aleksandrov, Vladimir Peller

For a pair $(A, B)$ of not necessarily bounded and not necessarily commuting self-adjoint operators and for a function $f$ on the Euclidean space $R^{2}$ that belongs to the in…

Functons of perturbed pairs of dissipative operators

Aleksei Aleksandrov, Vladimir Peller

Let $f$ be a function in the inhomogeneous analytic Besov space $B_{\infty, 1}^{1}$ . For a pair $(L, M)$ of not necessarily commuting maximal dissipative operators, we define the funct…
