Abstract
Let \((X, d, \mu)\) be a space of homogeneous type. Let \(T_{1}, T_{2}\) be singular integral operators with nonsmooth kernels. By establishing sparse domination, we obtain quantitative boundedness for the composite operator \(T_{1}T_{2}\) on \(L^{p}(X, \omega)\) with \(\omega\in A_{p}\) and the weighted endpoint estimate for the composite operator \(T_{1}T_{2}\).
