The dispersive properties of high order finite element schemes are analyzed in the setting of the Helmholtz equation, and an explicit form of the discrete dispersion relation is obtained for elements ...

Abstract: Wave motion lies at the heart of many disciplines in the physical sciences and engineering. For example, problems and applications involving light, sound, heat, or fluid flow are all likely ...

Dispersion is an important statistical measure that quantifies the range of outcomes among the components of an index during a specific period. The S&P 500 Realized Dispersion Indices offer two ...
