The Ghost-Node Process

Self-adaptive compact operators constitute a powerful tool for the unobstructed realization of higher order methods at boundary and material interfaces [52-58]. Having determined the basic form of their central version in Chapter 3, namely (3.50) and (3.51), the particular section 

Obviously, the preceding algorithm can be generalized to the construction of Mill-order compact operators LDy - For example, using more terms in the Pade approximation (4.28), the fifth-order member is given by
