Characterization of the-solutions of Multi-dimensional Two-direction Refinement Equation
Yan Wei-ju · Journal of Yulin University · 2015
In this paper,we study the-solutions multi-dimensional two-direction refinement equation. We characterize the basic properties of-solutions by Fourier transform method and iterated function systems. Moreover,we prove that any-solutions of the two-direction refinement equation are constant sign on its support. The theory of two-direction wavelet is developed.
