Extension of the lifted operator theorem to matrix Muckenhoupt weights

Let 1<p<1<p<\infty and let W=(wij) ⁣:Rn×RmCN×NW=(w_{ij})\colon \mathbb{R}^n\times \mathbb{R}^m\to\mathbb{C}^{N\times N} be a matrix weight in the set of Muckenhoupt weights Ap(N,Rn×Rm)A_p(N,\mathbb{R}^n\times \mathbb{R}^m). Let TKT_K be the operator lifted to the vector-valued setting, where the scalar kernel KK is of the type considered in Theorem

.Matrixweightextensionconjecture.TheconclusionofCorollary. **Matrix-weight extension conjecture.** The conclusion of Corollary

holds true for any such matrix weight WW; in particular, TKT_K is bounded on Lp(Rn×Rm,W)L^p(\mathbb{R}^n\times\mathbb{R}^m,W). This would remove the technical obstacles to lifting the scalar result to the full matrix-weighted setting; the supplied text does not indicate whether the assertion has been proved or remains open.
