摘要：

Let A be a d x d expansive matrix with vertical bar detA vertical bar = 2. This paper addresses Parseval frame wavelets (PFWs) in the setting of reducing subspaces of L-2 (R-d). We prove that all semi-orthogonal PFWs (semi-orthogonal MRA PFWs) are precisely the ones with their dimension functions being non-negative integer-valued (0 or 1). We also characterize all MRA PFWs. Some examples are provided. (C) 2011 Elsevier Inc. All rights reserved.
