Furthermore, we expand the utilization of this.technique to the C-ty.e Kadomts.v–Petvias.vili(CKP) equation, leading to the derivation of decompos.tion s.lutions. B?cklund trans.ormations. and the Lax pair s.ecific to this.*** res.lts.obtained not only.unders.ore the efficacy.of the propos.d approach, but als. highlight its.potential in offering a profound comprehens.on of integrable behaviors.in nonlinear s.0}tems.
