Nonhomogeneous Wavelet Dual Frames and Extension Principles in Reducing Subspaces
It can be seen from the literature that nonhomogeneous wavelet frames are much simpler to characterize and construct than homogeneous ones. In this work, we address such problems in reducing subspaces of L2ℝd. A characterization of nonhomogeneous wavelet dual frames is obtained, and by using the cha...
