On the complexity of checking semantic equivalences between pushdown processes and finite-state processes
Simulation preorder/equivalence and bisimulation equivalence are the most commonly used equivalences in concurrency theory. Their standard definitions are often called strong sim...

Meeting the deadline: on the complexity of fault-tolerant continuous gossip
In this paper, we introduce the problem of Continuous Gossip in which rumors are continually and dynamically injected throughout the network. Each rumor has a deadline, and the go...
