Nonhomogeneous Wavelet Bi-frames for Reducing Subspaces of \(H^s(K)\) and their Characterization
摘要
Bhat in Annal. Univ. Craiova, Math. Comp. Scien. Series 49: 2(2022), 401-410 has studied nonhomogeneous wavelet bi-frames in Sobolev spaces on local fields of positive characteristic. In this paper, we used the same platform to characterize nonhomogeneous wavelet bi-frames for the reducing subspaces of Sobolev spaces over local fields of positive characteristics.
