Dispersive Properties for Discrete Schrödinger Equations [PDF]
Journal of Fourier Analysis and Applications, 2011 In this paper we prove dispersive estimates for the system formed by two coupled discrete Schr dinger equations. We obtain estimates for the resolvent of the discrete operator and prove that it satisfies the limiting absorption principle. The decay of the solutions is proved by using classical and some new results on oscillatory integrals.

The Effect of Viscosity and Heterogeneity on Propagation of G–Type Waves
International Journal of Applied Mathematics and Computer Science, 2017 Earthquakes yield motions of massive rock layers accompanied by vibrations which travel in waves. This paper analyses the possibility of G-type wave propagation along the plane surface at the interface of two different media which is assumed to be ...

Dispersion Estimates for Spherical Schrödinger Equations [PDF]
Annales Henri Poincaré, 2016 The authors consider a one-dimensional Schrödinger equation with a real integrable potential and a given angular momentum, with the goal of providing dispersive decay solution estimates for the resulting differential equations. The behavior of the Jost function near the edge of the continuous spectrum is also studied.

Calculating Water Wavelength Using Dispersion Relation and Approximation
Undergraduate Journal of Mathematical Modeling: One + Two, 2019 The dispersion relation equation is used to directly compute wave number and wave length to compliment water wave pressure sensor readings. Waves are measured to help coastal engineering to better mitigate coastal infrastructures.
