Reducibility of 1-d Quantum Harmonic Oscillator Equation with Unbounded Oscillation Perturbations
Zhenguo Liang, Jiawen Luo
We build a new estimate relative with Hermite functions based upon oscillatory integrals and Langer's turning point theory. From it we show that the equation $$ i \partial_t u =-\p…

Three-dimensional solutions for the geostrophic flow in the Earth's core
Colin M. Hardy, Philip W. Livermore, Jitse Niesen +2
In his seminal work, Taylor (1963) argued that the geophysically relevant limit for dynamo action within the outer core is one of negligibly small inertia and viscosity in the magn…
