We recently introduced a class ofgraded discrete Lax pairs and studied the associated discrete integrable systems (lattice equations). In this paper, we introduce the corresponding Yang–Baxter maps. Many well-known examples belong to this scheme forN=2, so, forN≥3, our systems may be regarded as generalizations of these. In particular, for eachNwe introduce a class of multi-component Yang–Baxter maps, which includeHBIII(of Papageorgiouet al.2010SIGMA6, 003 (9 p). (doi:10.3842/SIGMA.2010.033)), whenN=2, and that associated with the discrete modified Boussinesq equation, forN=3. ForN≥5 we introduce a new family of Yang–Baxter maps, which have no lower dimensional analogue. We also present new multi-component versions of the Yang–Baxter mapsFIVandFV(given in the classification of Adleret al.2004Commun. Anal. Geom.12, 967–1007. (doi:10.4310/CAG.2004.v12.n5.a1)).
