Abstract

We give an extension of Rubio de Francia's extrapolation theorem for functions taking values in UMD Banach function spaces to the multilinear limited range setting. In particular we show how boundedness of an mm-(sub)linear operator T:Lp1(w1p1)××Lpm(wmpm)Lp(wp)T:L^{p_1}(w_1^{p_1})\times\cdots\times L^{p_m}(w_m^{p_m})\to L^p(w^p) for a certain class of Muckenhoupt weights yields an extension of the operator to Bochner spaces Lp(wp;X)L^{p}(w^p;X) for a wide class of Banach function spaces XX, which includes certain Lebesgue, Lorentz and Orlicz spaces. We apply the extrapolation result to various operators, which yields new vector-valued bounds. Our examples include the bilinear Hilbert transform, certain Fourier multipliers and various operators satisfying sparse domination results.
