Approximated factorizations for kernels involved in the scattering due to a wedge at skew incidence

The theory of the factorization is better mathematically founded in comparison to the theory of the difference equations. This aspect is particularly important when no closed form solutions of the difference equations are available or even possible, and approximated techniques become necessary to overcome the problem. According to the opinion of the authors, approximated factorizations face these problems in a more suitable and effective way. Some approximated factorization techniques related to wedge problems have been addressed.
