Abstract
A method is presented of treating the meson cloud around the nucleon. The meson cloud is described in terms of the free field operators which coincide, on the world point on the space-like surface, with the usual field operators in the Heisenberg representation. In the second and the third sections, the relation between the field and its source on an arbitrary space-like surface is studied. The fourth and fifth sections are concerned with the method of the phenomenological investigation of the meson cloud in our formalism and with the treatment of the problem of the multiple production of mesons and the magnetic moment of the nucleon-meson system. This treatment of the multiple production of mesons is shown to be the covariant generalization of Bloch-Nordsiecks' method for the multiple production of low energy photons.
