✦ Synopsis

The (m+1) dispersion coefficients, which define the (m) th dispersion approximation to the transverse average of the solution of the convective diffusion equation, can be gotten on exacting equality of the first (m+1) moments of the solution and its approximation We establish the equivalence of the Hermite and power moments in the construction of dispersion approxΔ±mations
