No small hairs in anisotropic power-law Gauss-Bonnet inflation
Tuan Q. Do, Sonnet Hung Q. Nguyen
We will examine whether anisotropic hairs exist in a string-inspired scalar-Gauss-Bonnet gravity model with the absence of potential of scalar field during the inflationary phase.…
Anisotropic power-law inflation in a two-scalar-field model with a mixed kinetic term
Tuan Q. Do, Sonnet Hung Q. Nguyen
We examine whether an extended scenario of a two-scalar-field model, in which a mixed kinetic term of canonical and phantom scalar fields is involved, admits the Bianchi type I met…
Canonical description of incompressible fluid -- Dirac brackets approach
Sonnet H. Q. Nguyen, Lukasz A. Turski
We present a novel canonical description of the incompressible fluid dynamics. This description uses the dynamical constraints, in our case reflecting "incompressibility" assumptio…
Recursive properties of Dirac and Metriplectic Dirac brackets with Applications
Sonnet Q H Nguyen, Lukasz A Turski
In this article, we prove that Dirac brackets for Hamiltonian and non-Hamiltonian constrained systems can be derived recursively. We then study the applicability of that formulatio…
On the Dirac Approach to Constrained Dissipative Dynamics
Sonnet Q H Nguyen, Lukasz A Turski
In this paper, we propose a novel algebraic and geometric description for the dissipative dynamics. Our formulation bears some similarity to the Poisson structure for non-dissipati…
