This work presents a general framework for approximating advection-diffusion equations based on principles of scale separation. A two-level decomposition of the discrete approximation space is performed and the local problem is modified to capture both local and nonlocal discontinuities. The new fea
differential equations of fractional order a b s t r a c t The variational iteration method is widely used in approximate calculation. The main difficulty of the method is to identify the Lagrange multiplier, k, for differential equations of fractional order, especially of high order, where the pro
