We speculate that there exist phase transition of orders greater than two as there is no known physical reason why such transitions should not exist in nature since they certainly exist in a number of theoretical models like quantum chromodynamics (QCD), lattice field theory and statistical physics [13].
that maps lattice field theory into the continuum field theory, where these operations are defined by the following.
