Oblique multiwavelets in Hilbert spaces
Wai-Shing Tang · Proceedings of the American Mathematical Society · 1999
In this paper, we elucidate the relationship between two consecutive levels of a multiresolution in the general setting of a Hilbert space. We first prove a result on an extendability problem and then derive, as a consequence, characterizations of oblique multiwavelets in a Hilbert space.
