  • Chern-Simons term in the geometric theory of defects 
    Katanaev M. (2017)
    © 2017 American Physical Society. The Chern-Simons term is used in the geometric theory of defects. The equilibrium equations with δ-function source are explicitly solved with respect to the SO(3) connection. This solution ...
  • Cosmological models with homogeneous and isotropic spatial sections 
    Katanaev M. (2017)
    © 2017, Pleiades Publishing, Ltd.The assumption that the universe is homogeneous and isotropic is the basis for the majority of modern cosmological models. We give an example of a metric all of whose spatial sections are ...
  • Gauge Parameterization of the n-Field 
    Katanaev M. (2019)
    © 2019, Pleiades Publishing, Ltd. We propose a gauge parameterization of the three-dimensional n-field using an orthogonal SO(3) -matrix, which, in turn, is defined by a field taking values in the Lie algebra so(3) ...
