Inverse construction of exact atmospheric models and the 3.7--4.4\,mHz acoustic resonances
O. V. Kaptsov
Large explosive eruptions and earthquakes excite atmospheric oscillations near 3.7 and 4.4\,mHz that couple to the solid Earth. For vertically propagating linear acoustic--gravity…

Exact Harmonic Dimensional Reduction and Conformal Lifting for Multicomponent Nonlinear Schrödinger Systems
O. V. Kaptsov
A harmonic dimensional reduction framework is developed for systems of coupled nonlinear Schrödinger-type equations with stationary transverse trapping potentials…
