Analytic solutions for coupled linear perturbations
Analytic solutions for the evolution of cosmological linear density perturbations in the baryonic gas and collisionless dark matter are derived. The solutions are expressed in a closed form in terms of elementary functions, for arbitrary baryonic mass fraction. They are obtained assuming Ω = 1 and a time independent comoving Jeans wavenumber, kJ . By working with a time variable τ ≡ ln(t), the ...
متن کاملAnalytic Solutions for Cosmological Perturbations in Multi-dimensional Space-time * †
We obtain analytic solutions for the density contrast and the anisotropic pressure in a multi-dimensional FRW cosmology with collisionless, massless matter. These are compared with perturbations of a perfect fluid universe. To describe the metric perturbations we use manifest gauge invariant metric potentials. The matter perturbations are calculated by means of (automatically gauge invariant) f...
متن کاملBlow-up Solutions for Linear Perturbations of the Yamabe Equation
For a smooth, compact Riemannian manifold (M, g) of dimension N ≥ 3, we are interested in the critical equation ∆gu+ ( N − 2 4(N − 1) Sg +εh ) u = u N+2 N−2 in M , u > 0 in M , where ∆g is the Laplace–Beltrami operator, Sg is the Scalar curvature of (M, g), h ∈ C (M), and ε is a small parameter.
متن کاملSensitivity of Solutions of Linear Pdae's with Respect to Perturbations
For initial boundary value problems (IBVPs) of linear partial diierential{algebraic equations we study the innuence of perturbations in the data on the numerical solution of the problems. First we investigate for initial value problems a speciic solution representation from an analytic point of view. This can be extended to certain IBVPs with the result that we can easily determine the order of...

(1) d/dxX(z) = A{z)X{z), where X(z) is an n x 1 column vector and A(z) is an n x n matrix of singlevalued meromorphic functions in a neighbourhood of the (isolated) singular point 0. Sometimes we write A instead of A(z) but we always consider a matrix of functions with such a notation unless explicitly stated otherwise. Each fundamental solution matrix for (1) can be represented near zero as (2...
