Linear and nonlinear tails II: exact decay rates in spherical symmetry

Nikodem Szpak, Piotr Bizoń, Tadeusz Chmaj +1

We derive the exact late-time asymptotics for small spherically symmetric solutions of nonlinear wave equations with a potential. The dominant tail is shown to result from the comp…

Linear and nonlinear tails I: general results and perturbation theory

Nikodem Szpak

For nonlinear wave equations with a potential term we prove pointwise space-time decay estimates and develop a perturbation theory for small initial data. We show that the perturba…

Quantum mechanics as a spontaneously broken gauge theory on a U(1) gerbe

J. M. Isidro

Any quantum-mechanical system possesses a U(1) gerbe naturally defined on configuration space. Acting on Feynman's kernel exp(iS/h), this U(1) symmetry allows one to arbitrarily pi…
