Concurrency (or maybe rather parallelism (Harper)) is a joint property of several (maybe interacting) processes proceeding simultaneously. Here the word “simultaneously” indicates that the evolution of the participating processes is indexed along an irreversible directed object.
The processes can either be the nil process $0$, parallel execution $P \mid Q$, sending on channel $c$ and then continuing $\overline{c}\langle x \rangle.P$, receiving on channel $c$ and then continuing $c(x).P$, replicating a process $!P$ or introduction of a new name $(\nu x)P$.
in a wider sense also articles related to directed homotopy theory, e.g.
