On dual soft local function

Set theory is one of the tools that plays an effective role in both applied and practical fields. It was circulated and used to facilitate and treat many important scientific problems. It should be noted that we mention the fuzzy sets, which is a subset of X\times [۰,۱], the soft sets, which are a subset of E\times p(x), center sets, which are subsets of p(x)\times p(x) and the dual soft sets are subsets of E\times p(x)\times p(y), where E is the parameters of elements of X and Y. Here in this paper, the concepts of ideal and local function have been generalized to dual soft sets and the study of their impact within this field.
