Gravitational waves from oscillons in a generalized exponential plateau potential
Peter Lott, Tuan Q. Do
We study oscillon formation and gravitational wave production in a generalized exponential plateau inflationary potential. Using Floquet analysis, we identify parametric instabilit…
Unstable de Sitter inflationary solution in sixth-order gravity
Tuan Q. Do
A sixth-order gravity, which involves not only two leading terms, and , but also quadratic curvature terms along with cubic curvature ones, wi…
Effect of on the stability of de Sitter solution of the generalized Einsteinian cubic gravity
Tuan Q. Do
In this paper, we would like to investigate whether a generalized Einsteinian cubic gravity, in which three possible cubic interactions , , and are…
On the stability of de Sitter inflationary solution in the Starobinsky-Bel-Robinson gravity
Tuan Q. Do
We will present the way to derive a de Sitter inflationary solution within the so-called Starobinsky-Bel-Robinson gravity. Then, we will show by using the dynamical system method w…
A note on the area of event horizon of Kleinian black hole
Tuan Q. Do
We point out that the area of event horizon of Kleinian black hole is infinite due to the fact that its event horizon is not a sphere but a hyperboloid. Therefore, the usual interp…
