Add   Extension of the Chern-Simons theory: conservation laws, Lagrange structures, and stability
Authors: Kaparulin, Dmitry S. | Karataeva, I. Yu. | Lyakhovich, Simon L.
Source: Russian physics journal. 2017. Vol. 59, № 11. P. 1930-1936
Type: статьи в журналах
Date: 2017
Description: We consider the class of higher derivative 3d vector field models with the wave operator being a polynomial of the Chern–Simons operator. For the nth order theory of this type, we provide a covariant ... More
Add   Lifting a weak Poisson bracket to the algebra of forms
Authors: Lyakhovich, Simon L. | Peddie, M. | Sharapov, Alexey A.
Source: Journal of geometry and physics. 2017. Vol. 116. P. 330-344
Type: статьи в журналах
Date: 2017
Description: We detail the construction of a weak Poisson bracket over a submanifold Σ of a smooth manifold M with respect to a local foliation of this submanifold. Such a bracket satisfies a weak type Jacobi iden ... More
Add   On the equivalence of two approaches to the construction of interactions in higher-derivative theories
Authors: Kaparulin, Dmitry S. | Lyakhovich, Simon L.
Source: Russian physics journal. 2017. Vol. 59, № 12. P. 2041-2047
Type: статьи в журналах
Date: 2017
Description: It is shown that two previously developed approaches to the construction of nonlinear interactions in higher-derivative theories (Eur. Phys. J., C74 (2014); J. Phys., A49 (2016)) lead to equivalent no ... More
