Abstract
In this paper, we define the \(L^\varphi \)-Lipschitz norm and \(L^\varphi \)-BMO norm of differential forms using Young functions, and prove the comparison theorems for the homotopy operator T on differential forms with \(L^\varphi \)-Lipschitz and \(L^\varphi \)-BMO norms. As applications, we give the \(L^\varphi \)-BMO norm estimate for conjugate A-harmonic tensors and the weighted \(L^\varphi \)-Lipschitz norm estimate for the homotopy operator T.
