Landau damping on expanding backgrounds
David Fajman, Liam Urban
We analyse the effect of expansion in Newtonian cosmology on the asymptotic behaviour of charged self-interacting plasmas close to Poisson equilibria. To this end, we study the Vla…
Quiescent Big Bang formation in dimensions
Liam Urban
In this paper, we study the past asymptotics of -dimensional solutions to the Einstein scalar-field Vlasov system which are close to Friedman-Lemaître-Robertson-Walker space…
On the past maximal development of near-FLRW data for the Einstein scalar-field Vlasov system
David Fajman, Liam Urban
We show that the maximal globally hyperbolic development of near-FLRW initial data for the Einstein scalar-field Vlasov system exhibits stable Big Bang formation in the collapsing…
Cosmic Censorship near FLRW spacetimes with negative spatial curvature
David Fajman, Liam Urban
We consider general initial data for the Einstein scalar-field system on a closed -manifold which is close to data for a Friedman-Lemaître-Robertson-Walker solution with…
Blow-up of waves on singular spacetimes with generic spatial metrics
David Fajman, Liam Urban
We study the asymptotic behaviour of solutions to the linear wave equation on cosmological spacetimes with Big Bang singularities and show that appropriately rescaled waves converg…
Space versus energy oscillations of Prüfer phases for matrix Sturm-Liouville and Jacobi operators
Hermann Schulz-Baldes, Liam Urban
This note considers Sturm oscillation theory for regular matrix Sturm-Liouville operators on finite intervals and for matrix Jacobi operators. The number of space oscillations of t…
