Special time.

We consider the time-domain boundary element method for exteriorRobin type boundary value problems for the wave equation. We applya space-time Galerkin method, present a priori and a posteriori errorestimates, and derive an h-adaptive algorithm in space and time withmesh renement driven by error indicators of residual and hierarchicaltype.Numerical experiments are also given which underline our theoreticalresults. Special emphasis is given to numerical simulations of the soundradiation of car tyres.
