In this work we deal with the notions of deadlock in the asynchronous
polyadic Pi-calculus. Based on the proposed definitions, we show that detecting
deadlock in the asynchronous polyadic pi-calculus is usually an undecidable
problem. However, when restricting the language by forbidding replicating input
prefixed processes, the detection turns out to be decidable, and a polynomial
deadlock detection algorithm is presented.
