Lax-wendroff theorem
WebA LAX-WENDROFF TYPE THEOREM 3 In many cases, L1 loc precompactness is difficult to prove — and might be false —, e.g. for unstructured grids or higher-order schemes for scalar conservation laws, not to mention schemes for systems of conservation laws. WebLax-Wendroff格式的数值通量表达式为： f j+21 = 21[f (uj)+f (uj+1)−λf ′(uj+21)(f (uj+1)− f (uj))] (LaxW) 这里的 λ 含义同上， uj+21 的值可以通过插值得到，我选的是线性插值，即， uj+21 = 21 (uj +uj+1) 。 ENO格式简介（先介绍标量） 使用有限体积法4阶ENO格式，时间方向用三阶TVDRunge-Kutta方法。 ENO格式是WENO格式的一个特例，我觉得可以先介 …

WebWe demonstrate that the reformulation of renormalization group (RG) flow equations as non-linear heat equations has severe implications on the understanding of RG flows in general.
