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 $\square \varphi ={\varphi }^p$ in odd $d\ge 5$ spatial dimensions. We show that for the quadratic non…
