【Abstract】 Some new operations of soft sets are defined and investigated.The concepts of the new soft subgroups and normal soft subgroups are given and some equivalent characterizations of the new soft subgroups are obtained.Furthermore,some preliminary properties of the new soft subgroups and normal soft subgroups under the different operations of soft sets are discussed.更多还原
