Abstract
Motivated by the composition of singular integral operators, we introduce a class of singular integral operators in the Euclidean space \(\mathbb {R}^{n}\) with kernels supported in surfaces in \( \mathbb {R}^{n}\times \mathbb {R}^{n}\). The surfaces are allowed to be very flat at the origin in \(\mathbb {R}^{n}\times \mathbb {R}^{n}\). The boundedness of the operators on \(L^{p}\) is proved under the assumption that the kernels are rough in \(L(\log L)^{2}(\mathbb {S}^{n-1}\times \mathbb {S}^{n-1})\).
