Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Conditions for a phase transition from the paramagnetic state to the modulated structure are found in a class of anisotropic Ising models with an
external magnetic field. The critical value of the external magnetic field is
obtained. Branching equations are derived and small branching theorems
are proven for commensurate and incommensurate configurations. |
