A note on late-time tails of spherical nonlinear waves
Piotr Bizoń, Tadeusz Chmaj, Andrzej Rostworowski
We consider the long-time behavior of small amplitude solutions of the semilinear wave equation in odd spatial dimensions. We show that for the quadratic non…

Global integrability of cosmological scalar fields
Andrzej J. Maciejewski, Maria Przybylska, Tomasz Stachowiak +1
We investigate the Liouvillian integrability of Hamiltonian systems describing a universe filled with a scalar field (possibly complex). The tool used is the differential Galois gr…
