摘要:
AbstractThis paper presents a general formalism for the description of topological objects created in quantum field systems with non‐Abelian symmetries. This formalism utilizes relations of differential form and therefore is suitable for the description of the local properties of the topological structure. The presentation of the general considerations is followed by several examples.Even when there is no gauge field, the analysis requires use of a gauge transformation matrix. This coincides with the usual gauge transformation matrix when a gauge field is introduce

摘要:
AbstractThe concept of the pion‐nucleus coupling constants is discussed. Methods of their determination are reviewed. These include: forward dispersion relations, extrapolation of differential cross sections to the poles in the angular variable, analysis of data on electromagnetic form factors with the use of the PCAC and CVC hypotheses, pion photoproduction at threshold and low‐ernergy theorems. Our present knowledge of the pion coupling to the He, Li, Be, C, N and O nuclei is summari

摘要:
AbstractThe extension of the “proper time” method to the statistical field theory is obtained. The procedure is used to calculate the “one loop” contribution to the thermodynamical potential in electrodynamics, when the electron positron gas is located in a combination of an inhomogeneous electrostatic field and an uniform magnetic one. Also, a “proper time” representation of the temperature Green function for this probl
