摘要:

AbstractThis review article outlines a number of efforts made over the past several decades to understand the physics of near critical many‐body systems. Beginning with the phenomenological theories of Landau and Ginzburg the paper discusses the two main routes adopted in the past. The first approach is based on statistical calculations while the second investigates the underlying nonlinear field equations. In the last part of the paper we outline a generalisation of these methods which combines classical and quantum properties of the many‐body systems stud

摘要:

AbstractThe elementary representations (ER) ofSU(2, 2) induced from the three non‐trivial parabolic subgroupsP0,P1,P2are explicitly constructed in two equivalent realizations. We exhibit a one‐to‐one correspondence between theP0andP2induced representations. The corresponding representations are equivalent. We also exhibit a two‐to‐one correspondence between theP1ERs and a subset of theP0ERs; however, the corresponding representations are only partially equivalent. The Knapp‐Stein integral intertwining operators are explicitly given for all representations in co
