Solos in Concert
Abstract:
We present a calculus of mobile processes without prefix or summation,
and using two different encodings we show that it can express both
action prefix and guarded summation. One encoding gives a strong
correspondence but uses a match operator; the other yields a slightly
weaker correspondence but uses no additional operators.

In the full version we also show that the expressive power of the solos calculus
is still retained by the subcalculus where actions carry at most two names.
On the contrary, expressiveness is lost in the solos calculus without match
and with actions carrying at most one name.
