| contents | In this article we discuss the long-time dynamics of the radial solutions to the focusing energy-critical wave equation in 5-dimensional space. We give some details about the asymptotic behaviour, topological structure and time evolution of the non-radiative solutions to this equation. As an application we prove a quantitative version of soliton resolution theorem for solutions defined for all time $t>0$, which immediately verifies the soliton resolution conjecture in the radial case, without a priori boundedness assumption on the energy norm of solution as time tends to infinity. The main tool of this work is the radiation theory of wave equations and the major observation of this work is a correspondence between the radiation and the soliton collision behaviour of solutions. |
