摘要
Inhomogeneous solutions (pseudoparticles) for the classical two-dimensional ferromagnet are found explicitly. By the appearance of pseudoparticles the correlation function changes over from power law decay to an exponential one. Pseudoparticles do not contribute to the propagating part of the equation of motion. © 1979.
