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 ...

Let µ bea Borei measure on ℝd which may be non doubling. The only condition that µ must satisfy is µ(Q) ≤ c₀l(Q)n for any cube Q ⊂ ℝd with sides parallel to the coordinate axes and for some fixed n ...

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 ...
