In this paper, we introduce a class of maximal functions along twisted surfaces in Rn ×Rm of the form {(φ(|v|)u, ϕ(|u|)v): (u, v) ∈ Rn ×Rm }. We prove Lp bounds when the kernels lie in the space Lq (Sn−1 ×Sm−1). As a consequence, we establish the Lp boundedness for such class of operators provided that the kernels are in L log L(Sn−1 ×Sm−1) or in the Block spaces Bq0,0 (Sn−1 ×Sm−1) (q > 1).
