Ali The research started from Salama's generalization to both ideal and local function through NCSs. We presented some results and properties to reinforce the concept of the generalized local function, which though its properties was used to deduce the properties of the 𝜓Ν𝐶- operator that we generalized through NCSS. 2025 2025 70 75 10.54216/IJNS.250307 https://www.americaspg.com/articleinfo/21/show/3243
