Process Equivalences as Global Bisimulations
: Bisimulation can be defined in a simple way using coinductive methods, and has rather pleasant properties. Ready similarity was proposed by Meyer et al. as a way to weakening the...

Decision Oracles are Equivalent to Matching Oracles
One of the key directions in complexity theory which has also filtered through to cryptographic research, is the effort to classify related but seemingly distinct notions. Separa...

Bisimulation and Other Undecidable Equivalences for Lossy Channel Systems
Lossy channel systems are systems of finite state automata that communicate via unreliable unbounded fifo channels. Today the main open question in the theory of lossy channel sy...

An equivalence for the Riemann Hypothesis in terms of orthogonal polynomials
We construct a measure such that if {pn(z)} is the sequence of orthogonal polynomials relative to that measure, then the Riemann Hypothesis with simple zeros is true if and only if...

Behavioural Equivalences on Finite-State Systems are PTIME-hard
The paper shows a logspace-reduction from the boolean circuit value problem which demonstrates that any relation subsuming bisimilarity and being subsumed by trace preorder (i.e.,...
