Schrödinger operators, typically formulated as −Δ + V where Δ denotes the Laplacian and V a potential function, are central to quantum mechanics and spectral theory. A key focus in recent ...
The Journal of Operator Theory endeavours to publish significant articles in all areas of operator theory, operator algebras and closely related domains. All accepted manuscripts are carefully ...
We show that the product BMO space can be characterized by iterated commutators of a large class of Calderón–Zygmund operators. This result follows from a new proof of boundedness of iterated ...
