我们建立了具有附加结构的非紧框架的扩张定理,即,由算子酉群和投射酉表示生成的框架。这推广了以前的扩张结果Parseval框架由于汉和拉森和Gabardo和汉。我们还扩展了Parseval小波的扩张定理,由于Dutkay,韩,Picioroaga,和太阳,通过确定最佳类的框架小波的扩张成正交小波是可能的。
We establish dilation theorems for non-tight frames with additional structure, i.e., frames generated by unitary groups of operators and projective unitary representations. This generalizes previous dilation results for Parseval frames due to Han and Larson and Gabardo and Han. We also extend the dilation theorem for Parseval wavelets, due to Dutkay, Han, Picioroaga, and Sun , by identifying the optimal class of frame wavelets for which dilation into an orthonormal wavelet is possible.
