中文摘要：A nonlocal coupled Kadomtsev–Petviashivili(ncKP)system with shifted parity(${\hat{P}}_{s}^{x}$)and delayed time reversal(${\hat{T}}_{d}$)symmetries is generated from the local coupled Kadomtsev–Petviashivili(cKP)system.By introducing new dependent variables which have determined parities under the action of${\hat{P}}_{s}^{x}{\hat{T}}_{d}^{d}$,the ncKP is transformed to a local system.Through this way,multiple even number of soliton solutions of the ncKPI system are generated from N-soliton solutions of the cKP system,which become breathers by choosing appropriate parameters.The standard Lie symmetry method is also applied on the ncKPII system to get its symmetry reduction solutions.
