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 ...
Under the assumption that μ is a non-doubling measure on ℝd, the authors obtain the boundedness of commutators generated by Calderón-Zygmund operators or fractional integrals with Lipschitz functions ...
ServoTek Products Inc. announced the successful application of its TachSyn Series brushless DC tachometer/commutator within industrial motor speed monitoring applications. The high-accuracy TachSyn ...
