Center node: "on the complexity of linearizability"
  Abstract: It was shown in Alur et al. [1] that the problem of verifying finite concurrent systems through Linearizability is in EXPSPACE. However, there was still a complexity gap between the easy to obtain PSPACE lower bound and the EXPSPACE upper bound. We show in this paper that Linearizability is EXPSPACE-complete.
