摘要: Abstract The linked cluster series expansion proposed by Nickel is extended to the ground state and axial string tension of lattice gauge theory. Proofs these expansions applications Z2 U(1) theory in 2 + 1 dimensions are presented. We also propose a new finite scaling method based on linked-cluster test it against known results for utility studying more complicated theories emphasized.
