摘要:

AbstractThe change of the particle distribution in space‐time is analysed in the framework of quantum field theory. The formalism is turned out to be thermo field dynamics. The formulation suggests a unification of quantum field theory and statistical physic

摘要:

AbstractThe various types of nonlinear wave solutions in plasmas are reviewed. First, the generation, pro‐ pagation, and stability of solitary waves are demonstrated for some simple examples. Then, relevant two‐and three‐dimensional models for Langniuir solitons are proposed and investigated. The collapse as an effective dissipation mechanism in plasmas is discussed in detail. Finally, simple models of two‐dimensional vortex motion and their consequences are con

摘要:

AbstractUsing an elementary version of the inverse spectral theory, a review of quasiperiodic solutions of the (1 + 1) dimensional eubic Schrödinger equation in terms of Riemann's theta functions is given. The general theory is illustrated by simple examples. In particular, the kink and soliton limits, and their relations to Bäcklund transformations are discusse

摘要:

AbstractWe give function space realizations of all representations of the conformal superalgebrasu(2,2/N) and of the supergroupSU(2, 2 /N) induced from irreducible finite‐dimensional Lorentz andSU(N) representations realized without spin and isospin indices. We use the lowest weight module structure of oursu(2,2/N) representations to present a general procedure (adapted from the semisimple Lie algebra case) for the canonical construction of invariant differential operators closely related to the reducible (indecomposable) representations. All conformal supercovariant derivatives are obtained in this way. Examples of higher order invariant differential operators are give
