摘要:
Let M be a d x d expansive matrix, and FL (2)(Omega) be a reducing subspace of L (2)(a"e (d) ). This paper characterizes bounded measurable sets in a"e (d) which are the supports of Fourier transforms of M-refinable frame functions. As applications, we derive the characterization of bounded measurable sets as the supports of Fourier transforms of FMRA (W-type FMRA) frame scaling functions and MRA (W-type MRA) scaling functions for FL (2)(Omega), respectively. Some examples are also provided.
