Multilayer multidimensional matter element system extension set and its properties

In order to study contradictory problems ofmultilayer multidimensional complex systems, based on the concept of n-dimensional matter element extension set, the concepts of multilayer multidimensional matter element system extension set and its positive field, negative field, zero boundary and its extension field as well as its stable field were given. The properties, intersection and union operations of multilayer multidimensional matter element system extension set were also discussed.
