One-Sided and Parabolic BLO Spaces with Time Lag and Their Applications to Muckenhoupt Weights and Doubly Nonlinear Parabolic Equations
Weiyi Kong, Dachun Yang, Wen Yuan
In this article, we first introduce the one-sided BLO space and characterize it, respectively, in terms of the one-sided Muckenhoupt class $A_1^+(\math…

Parabolic Extrapolation and Its Applications to Characterizing Parabolic BMO Spaces via Parabolic Fractional Commutators
Mingming Cao, Weiyi Kong, Dachun Yang +2
In this article, we establish the parabolic version of the celebrated Rubio de Francia extrapolation theorem. As applications, we obtain new characterizations of parabolic BMO-type…
