simple hypergraph projection [closed]












0












$begingroup$


I have been struggling quite a while with a question, which I suspect has a simple answer to:



I have a Graph G = (X,E,Ψ) with E being a family of subsets of X and Ψ being a mapping between two hyperedges (E is a hyperedge and X being a set of elements x1 ...xn)



I define subset X1 = X - X2.



Want i want to achieve is G' = (X1,E1,Ψ1). I want to give that function a name, since I need it to project a graph that has the same structure, in terms of mappings of hypergraphs, just with each hypergraph having less elements.



Help is very much appreciated.
