A minimal observable length is a common feature of theories that aim to merge quantum physics and gravity. Quantum mechanically, this concept is associated with a nonzero minimal uncertainty in ...

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 class of functions for which the commutator with the Hardy-Littlewood maximal function or the maximal sharp function are bounded on Lq are characterized and proved to be the same. Journal ...
