On the solution of the wave equation asymptotically localized at infinity
The explicit solutions of a wave equation in 3 dimensions found by Moses and Prosser (1990) and called 'bullets' are studied in detail. These solutions behave for t/spl rarr/+/spl infin/ as the characteristic function of an intersection of the annulus ct+a
