Bubble nucleation rate in fourth-order gravity.
We calculate the bubble nucleation rate in a fourth-order gravity theory whose action contains an R term, under the thin-wall approximation, by two different methods. First the bounce solution is found for the Euclidean version of the original action. Next, we use a conformal transformation to transform the theory into general relativity with an additional scalar field and then proceed to find ...
متن کاملA Simple Compact Fourth-Order PoissonSolver on Polar Geometry
We present a simple and efficient compact fourth-order Poisson solver in polar coordinates. This solver relies on the truncated Fourier series expansion, where the differential equations of the Fourier coefficients are solved by the compact fourthorder finite difference scheme. By shifting a grid a half mesh away from the origin and incorporating the symmetry constraint of Fourier coefficients,...
متن کاملA new duality transformation for fourth–order gravity
We prove that for non–linear L = L(R), G = dL/dR 6= 0 the Lagrangians L and L̂(R̂) with L̂ = 2R/G3 − 3L/G4, ĝij = G2 gij and R̂ = 3R/G2 − 4L/G3 give conformally equivalent fourth–order field equations being dual to each other. The proof represents a new application of the fact that the operator 2−R6 is conformally invariant. Gen. Rel. Grav. in print; KEY: Conformal relations in fourth–order gravity
متن کاملA Fourth Order Compact Di erence Scheme on
We present a fourth order compact nite diierence scheme on the face centered cubic (FCC) grids for the numerical solution of the two dimensional convection diiusion equation. The seven point formula is deened on a regular hexagon, where the strategy of directional derivative is employed to make the derivation procedure straightforward, eecient, and concise. A corresponding multigrid method is d...
متن کاملCosmological Vorticity in a Gravity with Quadratic Order Curvature Couplings
where Lm is the matter part Lagrangian. The gravitational field equation is presented in Eq. (2) of [1]. In contrast with the situation with generalized f(φ,R) gravity in Eq. (27), the gravity with Ricci-curvature square term in the action does not have the conformal symmetry to Einstein gravity [2]. In [1] we analysed the gravitational wave and derived a fourth order differential equation. How...
