For dispersion relations of the form ˙= ˙(k) stemming from (2), the sign of the real part of ˙ indicates whether the solution will grow or decay in time. If the real part of ˙(k) is negative for all kvalues, then any superposition of solutions of the form exp(˙t+ ikx) will also appear to decay.

Dispersion occurs whenever there is a process that changes the direction of light in a manner that depends on wavelength. Dispersion can occur for any type of wave and always involves wavelength-dependent processes. For a given medium, n increases as wavelength decreases and is greatest for violet light.

The term dispersion refers to the fact that the index of refraction of a medium is a function of frequency. ABSTRACTA simple explicit formula is presented here to approximate the dispersion relationship of linear water waves, which allows direct and accurate calculation of wavenumber k for a given freque III. Dispersion Relations A. Definition and Some Simple Examples Simply stated, a dispersion relation is the function ω(k) for an harmonic wave. For the simplest of waves, where the speed of propagation c is a constant, we see from Eqs. (3) and (4) that their dispersion relation is simply ω()k =ck.

Group speed. The fitting proceeds as follows: for each gene, an estimate of the dispersion is found which maximizes the Cox Reid-adjusted profile likelihood (the methods of Cox Reid-adjusted profile likelihood maximization for estimation of dispersion in RNA-Seq data were developed by McCarthy, et al. (2012), first implemented in the edgeR package in 2010); a trend line capturing the dispersion-mean While this dispersion relation has a simple analytical expression for \(\omega(k)\), the zeros of more general dispersion relations cannot be solved in closed form due to the mathematical complexity of \(\mathcal{D}\).

Therefore, the dispersion estimates reflect the variance in gene expression for a given mean value.
