Full abstraction for fair testing in CCS (expanded version)

Tom Hirschowitz.

In previous work with Pous, we defined a semantics for CCS which may both be viewed as an innocent form of presheaf semantics and as a concurrent form of game semantics. We define in this setting an analogue of fair testing equivalence, which we prove fully abstract w.r.t. standard fair testing&nbsp;[&hellip;]

An intensionally fully-abstract sheaf model for $\pi$ (expanded version)

Clovis Eberhart ; Tom Hirschowitz ; Thomas Seiller.

Following previous work on CCS, we propose a compositional model for the $\pi$-calculus in which processes are interpreted as sheaves on certain simple sites. Such sheaves are a concurrent form of innocent strategies, in the sense of Hyland-Ong/Nickau game semantics. We define an analogue of fair&nbsp;[&hellip;]
