“…Currently, there is a growing interest in wavelet analysis on studying and constructing (nonseparable) multivariate wavelets and framelets. There exist a huge amount of literature on wavelets, framelets and their many impressive applications, to only mention a tiny portion of them (in particular, multivariate framelets that are closely related to this paper), e.g., see [2,3,4,10,11,12,15,18,21,22,23,24,25,27,29,31,34,35,37] and many references therein. However, construction of multivariate wavelets and framelets are widely known as a challenging problem in the literature.…”
