Abstract

In this paper it is shown that for ΩLlogL(Sd1)\Omega\in L\log L(\mathbb{S}^{d-1}), the rough maximal singular integral operator TΩT_\Omega^* is of weak type LloglogL(Rd)L\log\log L(\mathbb{R}^d). Furthermore, for wA1w\in A_1 and ΩL(Sd1)\Omega\in L^\infty(\mathbb{S}^{d-1}), it is shown that TΩT_\Omega^* is of weak type LloglogL(w)L\log\log L(w) with weight dependence [w]A1[w]Alog([w]A+1),[w]_{A_1}[w]_{A_{\infty}}\log([w]_{A_{\infty}}+1), which is same as the best known constant for the singular integral TΩT_\Omega.
