Skorokhod's M1 topology for distribution-valued processes

Sean Ledger
2016 Electronic Communications in Probability  
Skorokhod's M1 topology is defined for c\'adl\'ag paths taking values in the space of tempered distributions (more generally, in the dual of a countably Hilbertian nuclear space). Compactness and tightness characterisations are derived which allow us to study a collection of stochastic processes through their projections on the familiar space of real-valued c\'adl\'ag processes. It is shown how this topological space can be used in analysing the convergence of empirical process approximations
