Abstract
We show Sigma^1_1-completeness of weak bisimilarity for PA (process algebra), and of weak simulation preorder/equivalence for PDA (pushdown automata), PA and PN (Petri nets). We also show Pi^1_1-hardness of weak omega-trace equivalence for the (sub)classes BPA (basic process algebra) and BPP (basic parallel processes).

The Full Abstraction of the UC Framework.

TL;DR: In this article, it was shown that security in the Universal Composability framework (UC) is equivalent to security in probabilistic polynomial time calculus ppc, under active and adaptive adversaries with synchronous and authenticated communication.

Refining the Undecidability Border of Weak Bisimilarity

TL;DR: It is shown that the weak bisimulation equivalence problem is undecidable even for normed subclasses of BPA and BPP extended with a finite constraint system.

Refining the Undecidability Border of Weak Bisimilarity.

TL;DR: In this paper, it was shown that weak bisimilarity is undecidable for pushdown processes (PDA), process algebras (PA), and multiset automata (MSA).

The Linear Time - Branching Time Spectrum II

TL;DR: In this paper, semantic equivalences and preorders for sequential systems with silent moves are studied, focusing on the ones that abstract from successful termination, stochastic and real-time aspects of the investigated systems, and the structure of the visible actions systems can perform.
