Coffman deadlocks in SCOOP
  In this paper we address the deadlock detection problem in the context of SCOOP - an OO-programming model for concurrency, recently formalized in Maude. We present the integration of a deadlock detection mechanism on top of the aforementioned formalization and analyze how an abstract semantics of SCOOP based on a notion of "may alias expressions" can contribute to improving the deadlock detection procedure.
