Weighted estimates for Bochner-Riesz operators on Lorentz spaces

We present new estimates in the setting of weighted Lorentz spaces of operators satisfying a limited Rubio de Francia condition; namely T is bounded on L-p(v) for every v in an strictly smaller class of weights than the Muckenhoupt class A(p). Important examples will be the Bochner-Riesz operators BR lambda with 0 < lambda. < (n - 1)/2, sparse operators, Hormander multipliers with a limited regularity condition and rough operators with Omega is an element of L-r(Sigma), 1 < r < infinity.
