چکیده
Consider a nonlinear wave equation for massless scalar field with self-interaction in the spatially flat de Sitter spacetime. We show that blow-up finite time occurs arbitrary power nonlinearity as well upper bounds of lifespan solutions. The condition is same accelerated expanding Friedmann–Lemaître–Robertson–Walker (FLRW) also results space derivative term.

Spherical linear waves in de Sitter spacetime
We apply Christodoulou’s framework, developed to study the Einstein-scalar field equations in spherical symmetry, to the linear wave equation in de Sitter spacetime, as a first step towards the Einstein-scalar field equations with positive cosmological constant. We obtain an integro-differential evolution equation which we solve by taking initial data on a null cone. As a corollary we obtain el...
متن کاملBlow-up of Solutions to Systems of Nonlinear Wave Equations with Supercritical Sources
In this article we focus on the life span of solutions to the following system of nonlinear wave equations: utt −∆u + g1(ut) = f1(u, v) vtt −∆v + g2(vt) = f2(u, v) in a bounded domain Ω ⊂ R with Robin and Dirichlét boundary conditions on u and v, respectively. The nonlinearities f1(u, v) and f2(u, v) represent strong sources of supercritical order, while g1(ut) and g2(vt) represent interior dam...
متن کاملSemilinear Wave Equations on Asymptotically De Sitter, Kerr-de Sitter and Minkowski Spacetimes
In this paper we show the small data solvability of suitable semilinear wave and Klein-Gordon equations on geometric classes of spaces, which include so-called asymptotically de Sitter and Kerr-de Sitter spaces, as well as asymptotically Minkowski spaces. These spaces allow general infinities, called conformal infinity in the asymptotically de Sitter setting; the Minkowski type setting is that ...
متن کاملGlobal solutions and finite time blow up for damped semilinear wave equations
A class of damped wave equations with superlinear source term is considered. It is shown that every global solution is uniformly bounded in the natural phase space. Global existence of solutions with initial data in the potential well is obtained. Finally, not only finite time blow up for solutions starting in the unstable set is proved, but also high energy initial data for which the solution ...
متن کاملBlow-up of solutions of nonlinear wave equations in three space dimensions.
Solutions u(x, t) of the inequality squareu >/= A|u|(p) for x epsilon R(3), t >/= 0 are considered, where square is the d'Alembertian, and A,p are constants with A > 0, 1 < p < 1 + radical2. It is shown that the support of u is compact and contained in the cone 0 </= t </= t(0) -|x - x(0)|, if the "initial data" u(x, 0), u(t)(x, 0) have their support in the ball|x - x(0)| </= t(0). In particula...
