Observation equivalence as a testing equivalence

open access: yesTheoretical Computer Science, 1987
A notion of testing is developed for transition systems with divergence. The forms of testing include traces, refusals, copying and global testing. Both denotational and operational formulations of testing are given. The equivalence based on this notion of testing is shown to coincide with observation equivalence.

Testing equivalence as a bisimulation equivalence

Formal Aspects of Computing, 1990
Abstract In this paper we show how the testing equivalences and preorders on transition systems may be interpreted as instances of generalized bisimulation equivalences and prebisimulation preorders. The characterization relies on defining transformations on the transition systems in such a way that the testing relations on the original ...

An Equivalence‐Theoretic Equivalent of the Axiom of Choice

Mathematical Logic Quarterly, 1986
Representability of unary partial operations by equivalence relations as introduced by the author [Z. Math. Logik Grundlagen Math. 29, 569-571 (1983; Zbl 0509.08002)] is shown to be equivalent to the axiom of choice.

Fuzzy equivalence relations and their equivalence classes

Fuzzy Sets and Systems, 2007
The authors investigate various properties of equivalence classes of fuzzy equivalence relations over a complete residuated lattice, and give certain characterizations of fuzzy semi-partitions and fuzzy partitions over a complete residuated lattice, as well as over a linearly ordered complete Heyting algebra.

Equivalence and Non-equivalence in Parallel Corpora

International Journal of Corpus Linguistics, 2001
The present paper shows how an aligned parallel corpus can be used to investigate the consistency of translation equivalence across the two languages in a parallel corpus. The particular issues addressed are the bidirectionality of translation equivalence, the coverage of multiword units, and the amount of implicit knowledge presupposed on the part of ...

Equivalent Equilibria

International Economic Review, 1988
The paper provides a way to formulate a general equilibrium model with both infinite time horizon and continuous uncertainty by \({\mathcal L}_{\infty}\)-commodity space, and provides a simple proof of the equivalence of equilibria in complete markets, incomplete markets with sequential trading, and incomplete markets with one-shot trades in single ...
