| Abstract: | 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. |
| Keywords: | Riesz basis biorthogonal system oblique projection multiwavelets |
