Abstract:
We show that strong bisimilarity of $CCS$ processes without summation and relabelling is preserved by any substition modulo the maintenance of internal channels, if the processes bear unique input locations. By this we understand a syntactic means of preventing that substitutions, which are in general not injective, cause synchronisation in one but not in the other of two originally bisimilar processes.
