Web2 de mai. de 2016 · The benefits of skew-symmetric differentiation matrices are much wider and, as argued in Sect. 3, they are a key to a stable approximation of kinetic equations. Yet, it has been proved in Iserles [ 13 ] that, assuming Dirichlet conditions, the highest order of a skew-symmetric differentiation matrix on a uniform grid is just two. WebThe matrix in (1.1) is skew symmetric, yet it is a sobering thought that this second-order approximation of the derivative is as good as it gets: no skew-symmetric highly influential journal
